final rationale
Mean of 5 draws (0.07, 0.07, 0.08, 0.08, 0.08). (0) Not resolved. The Senate.gov roster and McConnell's press-release page through late September 2026 show him as a sitting senator with no announcement of early departure. GovTrack shows him voting in 17 of 18 roll calls after September 22. (a) About three months remain, until January 3, 2027. (b) Status quo is No: he serves out the term, and the November 3 election picks his successor (Barr vs. Booker). (c) NO: he keeps attending intermittently, reaffirms his plan to finish the term as he did in his July 12 statement, and retires on schedule. (d) YES: a second acute health event (a fall, pneumonia, or death in office) forces resignation or vacates the seat. Death would plausibly count as 'otherwise vacates.' An early resignation to give a successor seniority is unlikely given Kentucky's 2024 no-appointment law. For an 84-year-old post-polio patient who was just hospitalized for months, a roughly 4-6% chance of death or incapacity in a quarter seems reasonable. Voluntary resignation adds very little, since he has resisted direct pressure from Beshear. I anchor on Polymarket's 8% (7/9 bid/ask) and shade slightly down because his attendance has recovered and no new health news has emerged since mid-September.

report: current state
- [2025-02-20] McConnell announced he would not seek reelection next year, ending a 40-year career in Congress, and said "My current term in the Senate will be my last." He did not announce early resignation, only non-candidacy for an eighth term. - [2026-06-14] McConnell was hospitalized after a fall at his home on June 14 ; EMS dispatch audio referenced possible cardiac arrest, though McConnell's doctors confirmed he did not have a heart attack or stroke, no tumors or hemorrhages, but he was briefly unconscious and taken to the hospital. - [2026-07-12] After weeks of sparse updates, McConnell's office said "Early in his hospitalization, he developed pneumonia, which responded rapidly to antibiotic treatment," and that the senator has "focused on physical therapy and strategies to reduce his risk of future falls." - [2026-07-27] Kentucky Gov. Andy Beshear publicly demanded McConnell either explain his long absence from the Senate and give details about his health, or resign — pressure, not an announcement by McConnell himself. - [2026-07-27] CNN noted the legal mechanics: if McConnell leaves office before his term ends, Kentucky would use a 2024 law that bars the governor from appointing a temporary senator and instead requires a special election — a process that has never been tested. - [2026-08-?] (reported ~67 days before Oct 4, i.e. late July) Beshear escalated again after McConnell's discharge, saying "I am calling on you to directly and verbally address the people of Kentucky and provide proof of your capacity to serve, or resign." - [2026-09-11] As the Senate prepared to reconvene, McConnell's office had still not publicly confirmed that he will appear on the Senate floor, though his statement said he would continue an intensive physical therapy regimen at home and remain engaged with his staff and colleagues on Senate business, and three months after his fall he still had not returned to the Senate floor. - [2026-09-14] McConnell physically returned to the Capitol: McConnell returned to the Senate on Monday and cast his vote after a more than three-month absence, saying "Today, I'll cast my first Senate vote since I took a bad fall back in June." He acknowledged his recovery had been "a long and frustrating process," complicated by "lingering effects of childhood polio," and said "I'm still not quite back to 100%." - [2026-09-30] Per GovTrack vote tracking, from June 15 to Sept. 17, 2026 McConnell missed 63 of 67 roll call votes (94%), he last voted on Sept. 30, 2026, and since Sept. 22, 2026 he has missed only 1 of 18 roll call votes (6%). This shows a return to near-normal attendance in the most recent two weeks. - [2026-10-03/04] Entertainment coverage (SNL cold open) satirized McConnell's frailty, reflecting ongoing public concern but no new factual health development; "With just over four weeks left until the midterm elections, Saturday Night Live went after the GOP's roster — with punishing takes on everyone from a buzzed Pete Hegseth to a barely-moving Mitch McConnell." This is satire, not a news event bearing directly on resignation. - [2026-10-04] No official statement from McConnell, his office, or the Senate indicates any intention to resign or vacate his seat before January 3, 2027; Republican incumbent Mitch McConnell is not seeking an eighth term but is currently listed as the sitting senator, with no vacancy declared. - Scheduled event before close: the November 3, 2026 general election will determine his successor (Andy Barr vs. Charles Booker) to be held on November 3, 2026, with Republican congressman Andy Barr and Democratic former state representative Charles Booker as nominees ; McConnell's term runs through January 3, 2027 regardless of the election outcome, per his own retirement timeline and the sibling question's deadline. BOTTOM LINE: McConnell suffered a serious health scare (fall, brief unconsciousness, pneumonia, three-month absence, intense pressure from Gov. Beshear to resign) but ultimately returned to the Senate floor in mid-September 2026 and has resumed near-full voting attendance through September 30, 2026, with no resignation announcement; this makes an early departure before January 3, 2027 look less likely than it did during the summer health crisis, though his advanced age (84) and fragile health keep nonzero risk alive. NOT FOUND: No evidence of any McConnell statement, office release, or Senate record in the last 7-14 days (since ~2026-09-20) indicating intent to resign or vacate his seat early; no confirmed update on his health status more recent than the September 30, 2026 vote record.
report: base rate
- [2025-02-20] McConnell announced on the Senate floor, on his 83rd birthday, that "I will not seek this honor an eighth time. My current term in the Senate will be my last," explicitly committing to serve out the term rather than resign early. [npr.org] - [2023-09-06] Historical pattern of denials: McConnell previously told reporters "I have no announcements to make on that subject," when asked if he plans to retire soon, and "I'm going to finish my term as leader and I'm going to finish my Senate term." He has repeated this pledge multiple times over 2023-2025, and it has held so far (axios.com). - [2026 CRS data, covering 101st–116th Congress, 1989-2020]: In that span, on average, two Senators and nine Members of the House of Representatives have left before the conclusion of a Congress , out of 100 senators — i.e., roughly a 2% per-Congress (2-year) base rate of any senator leaving early, for reasons including resignation, death, or expulsion (congress.gov/CRS R41428). - [Historical, 1789–2017]: Per CNN's review of Senate Historical Office records, senators resigned at much faster rates earlier in the country's history, with two in three resignations before the Civil War, while only 31 senators have resigned in the last half-century , mostly to take other government jobs rather than due to health—underscoring that early voluntary departures by sitting senators are historically rare events. - [Reference class: health-driven resignations] Precedent exists (e.g., senators resigning due to serious illness historically accounted for only 6% of all historical Senate resignations ), showing health-based resignation, while not unprecedented, is a minority pathway compared to career-advancement resignations. - [2026-07-06 to 2026-07-12] McConnell, 84, was hospitalized for over three weeks starting June 14, 2026, missing votes; Kentucky Governor Andy Beshear publicly pressed him for a health update. McConnell has not cast a vote since June 11, and his absence comes as Republicans are navigating a narrow Senate majority. He did not resign during this period. [washingtonpost.com, cnbc.com] - [2026-09-14] McConnell returned to the Senate after a 92-day absence, casting his first vote since the fall; the appearance ended months of questions about his condition and whether he would be able to return before his final term expires in January , resolving (at least temporarily) acute speculation about an early departure. [cnbc.com] - [2026-09-14] Even amid the health saga, reporting continued to frame his exit as scheduled: "McConnell has announced he will not seek re-election and is set to leave office when his term ends on January 3, 2027, making this one of his final acts as a sitting senator." [political.org] - [2026-07-08] Kentucky's own succession law adds friction against an early departure being politically "clean": if McConnell leaves office before his term ends, Kentucky would use a 2024 law that bars the governor from appointing a temporary senator and instead requires a special election — a process that has never been tested. This procedural novelty (no appointed caretaker) may create institutional/political pressure for him to hang on if at all able, rather than resign, since an untested special-election process would leave Kentucky's seat vacant for months. [cnbc.com] - [Market-adjacent indicator, snapshot ~2026-08-16] A secondary source summarizing Polymarket activity noted that as of that date McConnell's June 2026 fall requiring hospitalization for unconsciousness and mild pneumonia led to extended rehabilitation through early August 2026, during which he missed multiple Senate votes... Upon discharge from rehab, McConnell indicated he would continue recovery at home while remaining engaged with staff and colleagues on Senate matters, with no public signals of resignation or early departure... Calls from Kentucky Governor Andy Beshear and some Democrats for greater transparency on his capacity to serve or for resignation have not prompted any procedural moves, leadership changes, or shifts in McConnell's position. (This describes market commentary rather than official McConnell statements, and should be read only as a secondary account of the known facts, not as a probability input.) - [Base-rate comparison class] No sitting U.S. senator has resigned specifically due to age/health decline alone in the modern era while already a lame duck heading toward a scheduled retirement just months away; most age/health-linked exits historically have been via retirement announcements timed to the next election rather than mid-term resignation, consistent with McConnell's own February 2025 approach (choosing to announce non-candidacy rather than resign). BOTTOM LINE: The outside-view base rate for any sitting senator leaving office before a scheduled term end is low (roughly 2% of senators per two-year Congress historically, and voluntary health-driven resignations are a small minority even within that), and McConnell has repeatedly and consistently committed to finishing his term, surviving a serious 2026 hospitalization without resigning and returning to the Senate in September 2026. This reference class favors "No," though McConnell's advanced age (84), post-polio syndrome, and recent acute health crisis put him well outside the median senator and elevate his idiosyncratic risk above the generic base rate. NOT FOUND: No official Senate or McConnell-office statement indicating any intention to resign early as of early October 2026; no confirmed news of a second hospitalization or health crisis since his September 14, 2026 return; no specific actuarial/historical dataset isolating "senators who resigned solely due to declining health while already a confirmed lame duck."
report: yes case
YES means: Mitch McConnell formally announces he will leave the Senate before January 3, 2027, or otherwise vacates the seat (resignation, incapacitation-driven removal, or death) prior to that date — not merely reaffirming his already-announced retirement at term's end. - [2026-09-19] An expert in post-polio medicine told Newsweek that retrospective research suggests polio survivors found a 13.4 percent decline in motor-units, around seven times the rate of loss expected in non-disabled subjects in their age group, and separately that survivors may retain substantial function... even when someone has spent decades functioning independently... the physical toll can become more apparent as polio survivors age , a mechanism suggesting McConnell's fall/hospitalization-triggered decline may not simply reverse. https://www.newsweek.com/mitch-mcconnell-vote-childhood-polio-recovery-senate-12461927 - [2026-09-19] The same expert noted polio survivors "may take seven times longer than normal people to recover from the disuse atrophy associated with bedrest," implying McConnell's 92-day hospitalization/rehab stint could leave lasting functional deficits well past his September return. https://www.newsweek.com/mitch-mcconnell-vote-childhood-polio-recovery-senate-12461927 - [2026-09-19] Even after his return, McConnell has not resumed a full schedule: reporting noted that on one Thursday he McConnell's office said in July that the senator had experienced several falls during the year that were attributed to his post-polio condition. and that during a farm-bill committee vote he initially failed to respond to the clerk and had to be prompted by colleagues before voting — an echo of the pattern seen in Sen. Dianne Feinstein before her 2023 death in office. https://www.newsweek.com/mitch-mcconnell-vote-childhood-polio-recovery-senate-12461927 - [2026-09-19] McConnell himself signaled a partial, not full, return, saying he would do his "best to be present for tough votes" rather than committing to attend all votes — leaving open the possibility of further prolonged absences or a health setback serious enough to force resignation. https://www.newsweek.com/mitch-mcconnell-vote-childhood-polio-recovery-senate-12461927 - [2026-09-27] A physician's opinion column in the Washington Times argued Congress is " Our government has virtually no guardrails for situations such as this ," questioning whether McConnell, wheeled back in " After three months away from the Senate following a fall, hospitalization and pneumonia ," should have returned at all — reflecting continued outside medical concern that his frailty could deteriorate further and force an exit before term's end. https://www.washingtontimes.com/news/2026/sep/27/rushing-convalescent-octogenarian-mitch-mcconnell-back-work/ - [2026-09-19] Fox News/other reporting documented that during his absence a GOP colleague, Sen. Tuberville, publicly called for more information about his condition while Gov. Beshear repeatedly pressed him to "prove capacity to serve or resign," indicating continued political pressure that could tip toward a negotiated early departure if his health visibly worsens again. https://www.newsweek.com/mitch-mcconnell-vote-childhood-polio-recovery-senate-12461927 - [2026-10-04] Satirical and entertainment coverage (SNL, Daily Beast, Thought Catalog) continuing into October shows sustained, high-profile public narrative questioning his fitness, describing him as " has faced months of public scrutiny over his health after disappearing from view for 3 months following a hospitalization, and has recently been seen needing prompting from aides just to cast votes " — indicating the fitness-to-serve storyline remains live and could resurface quickly with any new incident. https://thoughtcatalog.com/xstockton/2026/10/snls-mitch-mcconnell-parody-is-indistinguishable-from-real-life/ - [2026-07-08/2026-09] Legal mechanics do not by themselves block a YES resolution: Kentucky's 2024 law (HB 622) requiring a special election rather than gubernatorial appointment creates political friction but does not prevent McConnell from resigning or dying in office; multiple outlets note that if a vacancy occurs after September 8—less than 56 days before the November 3 general election—the seat would likely remain vacant until the senator elected in November is sworn into office in January , meaning an incapacitation-driven resignation now would simply leave the seat vacant rather than legally barring McConnell from resigning. https://www.newsweek.com/mitch-mcconnell-health-dies-congress-kentucky-senator-replacement-12183303 - [path to YES] Given his age (84), compounded post-polio disuse atrophy, documented falls "throughout the year," a 92-day absence already occurring in 2026, and expert warnings that recovery could be multiples slower than normal, the single most plausible YES path is a second acute health event (fall, infection, hospitalization) between now and January 3, 2027 that either incapacitates him enough to force resignation, or results in his death in office — not a voluntary political resignation, which he and his office have consistently resisted even under direct pressure. BOTTOM LINE: No prerequisite step toward resignation has occurred; the strongest case for YES rests entirely on medical fragility (childhood polio, post-polio syndrome, documented multi-day falls, 92-day 2026 hospitalization, wheelchair use, slowed speech, and expert-flagged risk of disuse atrophy and recurrence) creating a non-trivial, idiosyncratic risk of a second health crisis or death before January 3, 2027, given McConnell's demonstrated pattern of repeated falls and infections within the same calendar year. NOT FOUND: No evidence of any second hospitalization, fall, or health decline since the September 30, 2026 vote record; no statement from McConnell or his office contemplating resignation under any circumstance, including the Beshear pressure campaign.
report: no case
YES means: Mitch McConnell formally announces an intention to leave the Senate before January 3, 2027, or otherwise vacates his seat (resignation, death, expulsion) prior to that date — a statement merely reaffirming his existing plan to retire at term's end would NOT count. - [2026-07-12] In an official press release on his own Senate website, McConnell stated directly: "part of my decision to retire at the end of my term this coming January was being honest about the demands of Senate work. But I still have unfinished business to complete on your behalf, and I have every intention of finishing the job you elected me to do." This is a primary-source, on-the-record reaffirmation of finishing the term — issued at the peak of his health crisis — which is exactly the type of statement the resolution criteria say "will not qualify" as a YES trigger. (mcconnell.senate.gov) - [2026-07-29] Even Gov. Beshear's own escalating pressure letters concede the mechanics work against an early exit: Beshear himself noted "Per the U.S. Constitution, senators can only be removed from their positions if they are expelled by a two-thirds vote of the entire Senate... Neither state political leaders, nor their constituents, can recall a senator from office before their term expires," underscoring that no external actor — not even a governor — can force McConnell out; only his own voluntary resignation or death/expulsion can trigger YES. (truthout.org) - [2026-07-29] A Senate GOP colleague publicly rebuffed the resignation pressure: asked about Beshear's ultimatum, "Sen. Rand Paul, R-Ky., defended McConnell," signaling no internal Republican momentum toward forcing or encouraging an early departure despite the health scare. (nbcnews.com) - [2026-09-10] Punchbowl News reported institutional confidence that McConnell's absence would end via a normal return, not a resignation: "Senate Republicans are tentatively preparing for Sen. Mitch McConnell (R-Ky.) to be back in the Capitol next week after a three-month absence," framed purely around a return-to-work timeline rather than succession planning. (punchbowl.news) - [2026-09-14] On his actual return, McConnell's own statement again signaled intent to keep serving, not depart: he said he had "assured Leader Thune that, as I continue with physical therapy on the advice of my doctors, I will do my best to be present for tough votes when our Conference needs me" — forward-looking commitment language, not an exit signal. (axios.com) - [2026-09-14] Press coverage of the return explicitly framed the resolved uncertainty as being about whether he'd finish his term, not whether he'd resign early: the Washington Post/Hill coverage of his long absence noted it had "fueled weeks of speculation about his health and whether he would return to the Senate before the end of his term in January" — speculation that his physical return answered in the negative (i.e., he is staying). (thehill.com) - [2024-era law, cited 2026-07-08/2026-07-29] The procedural friction described by CNN and reiterated by NOTUS — that Kentucky's 2024 law requires an untested special election with no caretaker appointment if McConnell leaves early — creates a disincentive for McConnell or Senate GOP leadership to engineer an early departure, since it would leave the seat vacant for months during a narrow-majority Congress, reinforcing status-quo inertia toward finishing the term. (notus.org) - [2026-09-30] GovTrack vote data (already cited in the base-rate report) shows McConnell missed only 1 of 18 votes since Sept. 22, 2026, indicating sustained, not one-off, return to active Senate duty rather than a brief appearance followed by withdrawal — this trend line, extended past the colleagues' Sept. 30 data, is the most current functional evidence that he remains an active, voting senator with no signs of an imminent exit as of early October 2026. - [Historical pattern reconfirmed] McConnell's documented history of weathering severe health-related speculation without resigning — the 2023 freeze-ups, the 2023 concussion/fall, and now the 2026 hospitalization — shows a consistent personal pattern: every prior health crisis produced reassurance statements of continued service (e.g., the 2023 "I'm going to finish my Senate term" quote already in the base-rate report) rather than resignation, and this pattern held again through the most severe episode yet in 2026. BOTTOM LINE: The strongest NO case rests on a primary-source quote from McConnell himself (July 12, 2026) explicitly committing to finish his term even mid-crisis, corroborated by his physical return to voting on September 14 and near-full attendance through late September, the constitutional/procedural barriers to forced removal, lack of GOP appetite to push him out, and a Kentucky succession law that disincentivizes an early, voluntary exit — all pointing toward NO absent a sudden new health collapse or death. NOT FOUND: No McConnell statement, Senate record, or Kentucky official communication from the last two weeks (since ~2026-09-20) was located indicating any change in health status or any new resignation-related development; no evidence of a second hospitalization since his September 14 return.

(0) Not resolved. The Senate.gov roster and McConnell's press-release page through late September 2026 show him as a sitting senator with no announcement of early departure. GovTrack shows him voting in 17 of 18 roll calls after September 22. (a) About three months remain, until January 3, 2027. (b) Status quo is No: he serves out the term, and the November 3 election picks his successor (Barr vs. Booker). (c) NO: he keeps attending intermittently, reaffirms his plan to finish the term as he did in his July 12 statement, and retires on schedule. (d) YES: a second acute health event (a fall, pneumonia, or death in office) forces resignation or vacates the seat. Death would plausibly count as 'otherwise vacates.' An early resignation to give a successor seniority is unlikely given Kentucky's 2024 no-appointment law. For an 84-year-old post-polio patient who was just hospitalized for months, a roughly 4-6% chance of death or incapacity in a quarter seems reasonable. Voluntary resignation adds very little, since he has resisted direct pressure from Beshear. I anchor on Polymarket's 8% (7/9 bid/ask) and shade slightly down because his attendance has recovered and no new health news has emerged since mid-September.

(0) Resolution check: nothing has resolved yet. The Senate.gov roster and McConnell's press page through late September 2026 show him serving, with no resignation announcement. GovTrack shows he missed only 1 of 18 votes after September 22, last voting September 30. (a) About three months remain until his term ends on January 3, 2027. (b) The status quo is No: he finishes his term and Andy Barr or Charles Booker takes the seat in January. McConnell has repeatedly committed to serving out the term, including a July 12, 2026 statement made mid-crisis. Kentucky's 2024 law bars a gubernatorial appointment, so resigning early to give his successor seniority would only leave the seat vacant. (c) NO scenario: he keeps attending through the lame-duck session, despite visible frailty and ongoing calls from Beshear to resign. (d) YES scenario: a second acute health event, such as a fall, infection or death in office, vacates the seat or forces a resignation. He is 84, has post-polio syndrome, was absent for 92 days in 2026, and has had repeated falls. Death in office would count as vacating, and that mortality risk over roughly 13 weeks plausibly runs about 4–6%. A voluntary resignation adds perhaps 1–2%. The Polymarket anchor of 8% (bid 7 / ask 9), down sharply since his return, is roughly consistent with this. I shade slightly lower because his attendance has stabilised and no new health incident has been reported.

The Senate roster still lists McConnell, and his official press-release page through September 23 shows no qualifying early-departure announcement or vacancy, so neither outcome is already settled. About three months remain until January 3, 2027, at 11:59 PM ET; YES requires an announcement specifying an earlier departure or an actual vacancy, supported by the designated official sources. I retain Polymarket’s live 8% YES anchor, within its 7–9% spread, because the research provides no clearly unpriced development warranting a departure. The status quo resolves NO: McConnell’s July 12 official statement explicitly committed to finishing his term, and his previously announced end-of-term retirement does not qualify. A plausible NO scenario is continued service despite intermittent medical absences, supported by his September 14 return reported by CBS and NPR and GovTrack’s record of participation in 17 of 18 votes from September 22 through September 30. A plausible YES scenario is another serious fall or infection leading to an early-resignation announcement or death; his age of 84, pneumonia, and prolonged rehabilitation sustain meaningful risk, although outside medical commentary does not establish an imminent exit. Kentucky’s reported prohibition on a caretaker appointment further discourages voluntary resignation, while the generally low historical early-departure rate supports NO but is poorly matched to his individual health risk. The official press-release listing is eleven days behind today, and continued roster membership alone cannot exclude an announcement of future early departure, so incomplete official-source coverage remains a modest uncertainty within the forecast.

I anchor on Polymarket's live 8% YES price (7% bid/9% ask) and retain it because the research reveals no clearly unpriced development warranting a departure. Neither outcome is already secured: Senate.gov still lists McConnell, and his official press-release archive through September 23 documents continued service rather than a qualifying early-exit announcement. Roughly three months remain until January 3, 2027, at 11:59 PM ET; YES requires an announcement specifying departure before that deadline or an actual early vacancy, established through the designated official sources. If nothing changes, NO wins, supported by McConnell's July 12 official commitment to finish his term, his September 14 return, and GovTrack's record of participation in 17 of 18 votes since September 22 through September 30. The low general Senate early-departure base rate and Kentucky's prohibition on caretaker appointments reinforce staying, although the average senator is a poor medical comparison for McConnell. A plausible NO scenario includes another prolonged medical absence without resignation, since incapacity or missed votes alone does not vacate his seat. The strongest YES scenario is another fall or infection leading to an officially announced early resignation or death, a meaningful risk given his age of 84, post-polio limitations, and recent lengthy hospitalization and rehabilitation. The retained 8% also allows for a qualifying announcement missed by the lagging official archive: recent voting cannot exclude a prospective resignation, while external medical commentary and satire provide no verified new deterioration.

(0) The resolving condition has not been met: the Senate roster still lists McConnell as serving, and his official press releases through September 23 show ongoing activity without an early-resignation announcement. (a) Approximately 91 days remain until January 3, 2027, at 11:59 PM ET, during which he would need to announce an earlier departure or otherwise vacate the seat for Yes. (b) If nothing changes, he completes his term as planned and the market resolves No; his July 12 official statement explicitly said he intended to finish the job, and he returned to the Senate on September 14. (c) The No scenario is that he continues his recently restored attendance—GovTrack shows only one missed vote out of 18 since September 22—and leaves when his term expires. (d) The clearest Yes scenario is another serious fall, infection, hospitalization, or death forcing departure during the remaining three months, given his age, post-polio complications, and recent 92-day medical absence. I remain anchored to Polymarket’s liquid 8% Yes price because the strong evidence favoring No, including his return and stated intent, is public and likely already incorporated, while his unusual medical fragility supports retaining a material tail risk.
4. Final plain mean of 5 draws
8% (74% confidence)
Yes: 8% No: 92%
Mean of 5 draws (0.07, 0.07, 0.08, 0.08, 0.08). (0) Not resolved. The Senate.gov roster and McConnell's press-release page through late September 2026 show him as a sitting senator with no announcement of early departure. GovTrack shows him voting in 17 of 18 roll calls after September 22. (a) About three months remain, until January 3, 2027. (b) Status quo is No: he serves out the term, and the November 3 election picks his successor (Barr vs. Booker). (c) NO: he keeps attending intermittently, reaffirms his plan to finish the term as he did in his July 12 statement, and retires on schedule. (d) YES: a second acute health event (a fall, pneumonia, or death in office) forces resignation or vacates the seat. Death would plausibly count as 'otherwise vacates.' An early resignation to give a successor seniority is unlikely given Kentucky's 2024 no-appointment law. For an 84-year-old post-polio patient who was just hospitalized for months, a roughly 4-6% chance of death or incapacity in a quarter seems reasonable. Voluntary resignation adds very little, since he has resisted direct pressure from Beshear. I anchor on Polymarket's 8% (7/9 bid/ask) and shade slightly down because his attendance has recovered and no new health news has emerged since mid-September.
