final rationale
Mean of 2 draws (0.65, 0.65). (0) Nothing has resolved. The election is Nov 3, 2026, and AP, Fox and NBC have not called the race (resolution-source read, Oct 13). (a) About three weeks remain until Election Day, and the result is usually called on election night or soon after. (b) Status quo: Acton (D) leads the poll averages by about 2–5 points (RCP +3.8, DDHQ +4.2, FiftyPlusOne +4.1, Pollsmax +2.1). Cook, Sabato and Inside Elections all moved the race to Toss-up, and every rating shift has been toward Democrats. The Polymarket anchor is 71.5%, up 17 points in 30 days, and Kalshi sits around 69–71%. (c) NO: Ohio's polls repeat the 2016/2018/2020/2024 pattern of understating Republicans by 2–4 points. Ramaswamy's roughly 2:1 cash-on-hand edge buys a late ad blitz, and Trump and Vance consolidate GOP voters in a Trump +11 state. The latest co/efficient (R) poll, Ramaswamy +2, could signal that tightening, and he wins narrowly. (d) YES: low Trump approval in Ohio (36–42%), Acton's edge with independents and a Democratic enthusiasm gap hold up. Brown's parallel lead points to a broad Democratic environment, so Acton wins by a few points, as in a 2006-style wave. The market looks a little rich against a lead that sits within a typical Ohio polling miss, and Ohio has a structural Republican lean and a record of Republican-favoring misses. I shade modestly below the 71.5% anchor rather than fully trusting the price.

Research loops, bottom lines
- current state: Acton leads most polls and averages by roughly 2–5 points, but the race is rated a Toss-up. Ohio leans Republican structurally, Ramaswamy has a large cash edge, and one recent Republican-aligned poll had him ahead. No race call or event before the close is scheduled beyond Election Day.
- base rate: The historical base rate favors Republicans. Democrats have lost every Ohio governor race since 2010, and Ohio is about R+10 on the 2024 presidential result. The only comparable Democratic win came in the 2006 midterm wave. Current polls, ratings and markets are a toss-up to Lean D, with the polling average at Acton +2 to +4 and markets at about 70%. Midterm environment and polling lean toward a Democratic win, while Ohio's partisan lean and a few polls with Ramaswamy ahead cut against it.
- yes case: The strongest YES case is a national environment worse for Republicans than Ohio's partisan lean, which shows up as Trump approval of 36–42% in Ohio, Democratic generic-ballot and enthusiasm edges, and both Democrats leading statewide polls. Acton has led the polling average for roughly a month, so YES needs only that this holds on Nov 3.
- no case: The strongest NO case rests on structure rather than current data. Ohio is Trump +11, Republicans have held the office since 2011, polls have overstated Democrats in Ohio by 2–4 points in recent cycles, and Ramaswamy has a large money advantage. Acton's lead is within a typical polling miss, and the early-vote Democratic skew is not a vote count.

report: current state
- [2026-10-13] The race is open-seat Ohio governor on Nov 3, 2026: Democrat Amy Acton (running mate David Pepper) against Republican Vivek Ramaswamy (running mate Rob McColley). The Libertarian on the ballot is Don Kissick. DeWine is term-limited. Democrats last won this office in 2006. https://en.wikipedia.org/wiki/2026_Ohio_gubernatorial_election
- [2026-10-08] Poll averages after the latest polls, all with Acton ahead: 270toWin Acton +5.5 (Oct 4), Decision Desk HQ +4.2 (Oct 8), FiftyPlusOne +4.1 (Oct 8). RCP average (Sept 1–Oct 6) is Acton 48.1, Ramaswamy 44.3. https://en.wikipedia.org/wiki/2026_Ohio_gubernatorial_election and https://www.realclearpolling.com/polls/governor/general/2026/ohio/ramaswamy-vs-acton
- [2026-10-08] Latest polls. CNN/SSRS (Sept 29–Oct 5, 760 LV): Acton 50, Ramaswamy 42. NYT/Siena (Sept 22–Oct 1): Acton 49, Ramaswamy 45. co/efficient (R) (Oct 5–6, 925 LV): Ramaswamy 45, Acton 43. That co/efficient poll was the first to show Ramaswamy ahead after five straight Acton leads. Marist (Sept 24–27) had Acton +6 and Suffolk (Sept 23–27) had Acton +9. A Big Data Poll (R) had Ramaswamy +1. https://www.newsweek.com/vivek-ramaswamy-gets-boost-after-five-ohio-polling-blows-in-a-row-12544047
- [2026-10-08] Ratings: Cook and Sabato's Crystal Ball both rate the race a Toss-up. Newsweek, citing both, says early voting is already underway. Cook moved it from Lean R to Toss-up on 2026-07-16. Ballotpedia (2026-09-23) listed Inside Elections at Tilt R and Sabato at Lean R at that time, so Sabato has since moved. https://www.newsweek.com/vivek-ramaswamy-gets-boost-after-five-ohio-polling-blows-in-a-row-12544047 and https://news.ballotpedia.org/2026/09/23/amy-acton-d-and-vivek-ramaswamy-r-to-face-off-in-toss-up-election-for-governor-of-ohio/
- [2026-10-12] Money: in Aug–Sept Acton raised $10.1M and Ramaswamy $5.6M. Cash on hand is Ramaswamy $48.7M and Acton $24.1M. Ramaswamy added $5.3M of his own money in September. https://www.nbc4i.com/news/your-local-election-hq/vivek-ramaswamy-amy-acton-rely-on-ohio-donors-in-last-stretch-of-campaigns-for-governor/ and https://www.yahoo.com/news/politics/articles/vivek-ramaswamy-amy-acton-rely-160000392.html
- [2026-10-13] Ohio Capital Journal: Acton out-raised Ramaswamy about 2-to-1 in September, but his $5M+ in personal loans over Aug–Sept leaves him ahead on cash. https://ohiocapitaljournal.com/2026/10/13/ramaswamy-loans-campaign-5-million-more-as-acton-outpaces-him-with-donors/
- [2026-09-02] Ramaswamy accepted CNN and WLWT debate invitations. Acton's campaign declined, and as of the Wikipedia page's latest update no debate between the nominees is scheduled. https://en.wikipedia.org/wiki/2026_Ohio_gubernatorial_election
- [2026-10-06] Suffolk and Marist both showed Acton leading among independents (64-27 and 57-32) and women. Acton's net favorability is about -1 against about -11 for Ramaswamy in the BGSU poll (reported Oct 2, fieldwork Sept 1–10). In the Suffolk/Marist report, 53% of respondents said they expected Ramaswamy to win. https://irontontribune.com/2026/10/06/two-polls-show-acton-lead-grows-over-ramaswamy/ and https://ohiocapitaljournal.com/2026/10/02/still-anyones-ball-game-bowling-green-poll-finds-statistical-tie-in-ohios-race-for-governor/ and https://fox8.com/news/two-polls-of-ohio-voters-show-amy-acton-ahead-of-vivek-ramaswamy-for-governor/
- [2026-10-03/08] Trump endorsed Ramaswamy and campaigned with him in Ohio in early October (a Vandalia rally on Oct 3, per Newsweek). The national environment is described as unfavorable to Republicans. Newsweek cites record-low Trump approval, and the CNN poll found 76% of Ohio voters attribute rising prices to Trump's policies. https://www.newsweek.com/vivek-ramaswamy-gets-boost-after-five-ohio-polling-blows-in-a-row-12544047
- [2026-08-13] Earlier risk to Acton: a Fox News poll on Aug 13 found 47% of Ohio voters viewed her negatively, up from 37% in June, after heavy Ramaswamy and allied attack ads (Acton's campaign says $50M+). The Democratic Governors Association planned a $9.4M ad campaign starting after Labor Day. https://signalohio.org/billionaire-jeff-yass-ohio-governor-race-november-election-2026/
- [2026-10-13] Context only (not this contract's own price): Polymarket's page snapshot shows Acton at 69% and Ramaswamy at 32%. Kalshi is reported at about 68–71% for Acton (Oct 8–9). Aggregator PoliAgg's model, generated 2026-10-10, gives Ramaswamy 89% (R+10.5), a big outlier from the poll averages. https://polymarket.com/event/ohio-governor-winner-2026 and https://parlaythepeople.com/2026/governor/ohio/ and https://poliagg.com/race/us-governor-2026-oh/
- [2026-11-03] Scheduled: Election Day is Nov 3, and the winner is inaugurated Jan 11, 2027. The market's resolution sources are AP, Fox and NBC, and none has called the race. https://en.wikipedia.org/wiki/2026_Ohio_gubernatorial_election
BOTTOM LINE: Acton leads most polls and averages by roughly 2–5 points, but the race is rated a Toss-up. Ohio leans Republican structurally, Ramaswamy has a large cash edge, and one recent Republican-aligned poll had him ahead. No race call or event before the close is scheduled beyond Election Day.
NOT FOUND: Sabato's and Inside Elections' current ratings from primary pages (only secondary sources), any new polls dated after Oct 6, any AP, Fox or NBC call, and any scheduled debate.
report: base rate
- [2026-11-03] The election is on Nov 3, 2026. Democrat Amy Acton faces Republican Vivek Ramaswamy for an open seat, because DeWine is term-limited. Wikipedia (fetched) says Democrats have not won an Ohio governor race since 2006. https://en.wikipedia.org/wiki/2026_Ohio_gubernatorial_election
- [2006-11-07] Reference class: the last Democratic win was Strickland in 2006, with 60.5% to 36.6%. It was an open seat in a national Democratic midterm wave against a GOP president, with scandal-hit GOP incumbents. https://en.wikipedia.org/wiki/2006_Ohio_gubernatorial_election
- [2010-11-02] Strickland lost his 2010 re-election bid 47.0% to 49.0%. Ohio has had Republican governors since 2011 (Kasich, then DeWine). DeWine won 62.4% in 2022 (Cook). https://en.wikipedia.org/wiki/Green_Party_of_Ohio
- [2026-10-06] Polling: the RCP average for 9/1–10/6 is Acton +3.8 (48.1 to 44.3). Recent polls: CNN Acton +8, NYT/Siena +4, Marist +6 (RV), YouGov +4, Suffolk +9. Big Data Poll had Ramaswamy +1 and co/efficient (R) had Ramaswamy +2. The RCP table could not be fetched in full, so the figures come from the search snippet. https://www.realclearpolling.com/polls/governor/general/2026/ohio/ramaswamy-vs-acton
- [2026-10-06] 270toWin's aggregate shows Acton ahead 49.3 to 46.3. Cook and Sabato both rate the race a Toss-up. https://irontontribune.com/2026/10/06/two-polls-show-acton-lead-grows-over-ramaswamy/
- [2026-10-06] Rating drift: Cook moved Ohio from Lean R (July 10) to Tilt R and then Toss-up (Oct 1). Inside Elections moved to Toss-up on Oct 1, having been Lean R in June. Sabato moved it from Leans R to Toss-up on Sep 22. Every shift has been toward Democrats. https://www.270towin.com/2026-governor-election/inside-elections-governor-2026
- [2026-10-09] Prediction markets: Kalshi 70.8% and Polymarket 69.2% for Acton on Oct 9. They were roughly even (50/50) in mid-August, moved to about 55–58% in September, and reached 68–69% by Oct 13. Markets are well above polling-based models. https://parlaythepeople.com/2026/governor/ohio/
- [2026-10-13] The Polymarket page shows Acton at 69% and Ramaswamy at 32% (prices sum above 100). Total volume was about $325K, which is thin. https://polymarket.com/event/ohio-governor-winner-2026
- [2026-10-10] Model disagreement: PoliAgg's model gives Acton only 11% (predicted R+10.5, which looks fundamentals-driven and conflicts with its own polling average of Acton +2 to +4). OddsShopper's seven-model price-blind panel gave Ramaswamy about 58% on Aug 7. Both are outliers relative to the markets. https://poliagg.com/race/us-governor-2026-oh/
- [2026-10-05] Context: Trump won Ohio by double digits in 2024 (Newsweek). Acton leads among independents (CNN +27). The national environment reportedly favors Democrats, with a low Trump approval rating and high gas prices. https://www.newsweek.com/vivek-ramaswamy-gets-boost-after-five-ohio-polling-blows-in-a-row-12544047
- [2026-09-21] Expectation gap: 53% of Marist respondents and 62% of BGSU respondents expect Ramaswamy to win. Acton has led in all major polls for about a month. https://www.wonderwall.com/politics/vivek-ramaswamy-faces-record-low-odds-winning-ohio-gubernatorial-race-amy-acton/
- [2026-10-13] Resolution timing: AP, Fox and NBC calls normally come on election night. In 2006 the race was called at poll close (7:30 pm). A close race could take longer, and certification is the fallback. https://en.wikipedia.org/wiki/2006_Ohio_gubernatorial_election
BOTTOM LINE: The historical base rate favors Republicans. Democrats have lost every Ohio governor race since 2010, and Ohio is about R+10 on the 2024 presidential result. The only comparable Democratic win came in the 2006 midterm wave. Current polls, ratings and markets are a toss-up to Lean D, with the polling average at Acton +2 to +4 and markets at about 70%. Midterm environment and polling lean toward a Democratic win, while Ohio's partisan lean and a few polls with Ramaswamy ahead cut against it.
NOT FOUND: Track-record data on how accurate Ohio polling has been (Ohio polls underestimated Republicans in 2016/2020/2024, but I did not verify this in this session). The RCP table and the Parlay page could not be fetched in full. No 538/Silver Bulletin-style model for this race was found. I did not find an independent aggregate of the Ohio governor result in past midterms.
report: yes case
YES means: Democrat Amy Acton wins the Nov 3, 2026 Ohio governor election, as called by AP, Fox and NBC or by official certification.
- [2026-09-24/27] Marist (1,298 RV) found Trump's Ohio approval at 42%. It found 41% saying their midterm vote is "against" Trump, against 25% "for" him, and 41% saying they are worse off financially. That is a structural driver of Acton's lead, not only candidate quality. Marist also showed Acton +6 and Brown +8. https://ohiocapitaljournal.com/2026/10/05/poll-dems-open-lead-in-two-ohio-races/
- [2026-10-05] The Ohio generic congressional ballot is D+3 in the same report, which is cited against a national D+8.5 on RCP. Acton is running ahead of the generic ballot in some polls. The report also cites the NYT Trump approval average at 37% and a data-center backlash. The NRSC's own August memo calls data centers an "anchor" on Husted. https://ohiocapitaljournal.com/2026/10/05/poll-dems-open-lead-in-two-ohio-races/
- [2026-10-01] The Senate race is a correlated path. Brown (D) leads Husted in the RCP average (9/1–10/6) by +3.1, and in CNN (Sept 29–Oct 5) 49–43. A Democratic strength that carries Brown also tends to carry Acton, and the CNN poll shows both Democrats ahead at the same time. https://www.realclearpolling.com/polls/senate/special-election/2026/ohio/husted-vs-brown
- [2026-10-01] InsiderAdvantage (R-leaning, 9/28–29, 1,200 LV) said Republican enthusiasm lags Democratic enthusiasm by 10 points, and that its numbers do not weight for enthusiasm. Even a GOP-friendly pollster sees a Democratic turnout edge. That is the opposite of the usual Ohio midterm pattern. https://insideradvantage.com/insideradvantage-ohio-senate-race-narrows-to-brown-up-by-one/
- [2026-10-08] CNN has Trump's Ohio approval at 36%. Trump and Vance have been campaigning in Ohio for Ramaswamy. The Hill says Republicans are fighting midterm headwinds, including the historic trend of the president's party losing between presidential cycles. https://www.yahoo.com/news/politics/articles/brown-holds-6-point-lead-145444042.html and https://thehill.com/homenews/campaign/6139956-ohio-governor-election-ramaswamy-acton/
- [2026-09/10] BGSU/YouGov (fieldwork Sept 1–10, reported Oct 2) has Acton 48, Ramaswamy 45, with independents Acton +11 (45–34). Women, young voters, Black and Hispanic voters favor her. Its favorability was Acton 41/47 against Ramaswamy 36/42, so she has a favorability edge despite the attack-ad spending. https://www.washingtonexaminer.com/news/campaigns/state/4729492/acton-ramaswamy-ohio-gubernatorial-polling/ and https://ohiocapitaljournal.com/2026/10/02/still-anyones-ball-game-bowling-green-poll-finds-statistical-tie-in-ohios-race-for-governor/
- [2025-12] Early trend: Emerson (Dec 2025) had Acton +1 (46–45), up 7 points from August 2025 (Ramaswamy +10). The ratings drift toward Democrats through 2026 is consistent with this. Women moved from 42–44 to 56–37 for Acton. https://www.yahoo.com/news/articles/democrat-gains-race-against-ramaswamy-110000432.html
- [2026-10-12] Ohio early in-person voting opened Oct 6, with strong turnout at the start (about 400 per hour at the Franklin County board). The Franklin County director expects turnout of about 55%, the same as in 2018, which was a Democratic-leaning midterm. That is a modest datapoint, not a partisan breakdown. https://www.10tv.com/article/news/politics/elections/early-voting-begins-across-ohio/530-7800500e-fd51-4100-89c1-baa54dd4f12e
- [2026-10-12] Most likely path to YES: the CNN, NYT, Marist, Suffolk and BGSU polls are about right. Acton wins independents by 11 to 27 points, holds Democratic and urban margins, and a low-approval Trump (36–42% in Ohio) depresses Republican turnout and drives some crossover, as in Brown's polling. Prerequisites: independents stay with her, her favorability survives Ramaswamy's cash advantage, and the polls are not a repeat of 2016/2020/2024 underestimation of Republicans. No scheduled event before Nov 3 is needed. https://www.realclearpolling.com/polls/governor/general/2026/ohio/ramaswamy-vs-acton
BOTTOM LINE: The strongest YES case is a national environment worse for Republicans than Ohio's partisan lean, which shows up as Trump approval of 36–42% in Ohio, Democratic generic-ballot and enthusiasm edges, and both Democrats leading statewide polls. Acton has led the polling average for roughly a month, so YES needs only that this holds on Nov 3.
NOT FOUND: Early-vote partisan breakdown from the Ohio Secretary of State dashboard (mail requests are down 26% from 2022, which cuts against this case). Any poll dated after Oct 8 and any AP, Fox or NBC call. The Hill and NBC4 pages could not be fetched in full, so those claims come from search snippets.
report: no case
YES means: Democrat Amy Acton wins the 2026 Ohio governor election, as called by AP, Fox and NBC or, failing that, by official certification.
- [2024-11-05] Ohio polls have missed in the Republican direction before. In 2024, 270toWin's pre-election average had Trump +7.7 and he won by just over 11 (Newsweek, Oct 2026). RCP's final Senate average was Moreno +1.7 and he won by 3.6. Both misses went the same way, about 2–3.5 points. A similar miss would cut Acton's +2 to +5 poll-average lead to roughly zero. https://www.newsweek.com/sherrod-browns-polling-lead-defies-ohios-republican-shift-12532271 and https://link.axios.com/click/36447235.515062/aHR0cHM6Ly93d3cucmVhbGNsZWFycG9sbGluZy5jb20vcG9sbHMvc2VuYXRlL2dlbmVyYWwvMjAyNi9vaGlvL2Jyb3duLXZzLW1vcmVubz91dG1fc291cmNlPW5ld3NsZXR0ZXImdXRtX21lZGl1bT1lbWFpbCZ1dG1fY2FtcGFpZ249bmV3c2xldHRlcl9heGlvc2FtJnN0cmVhbT10b3A/6456d95df25646b7e70dcfabB2662db7e
- [2026-10-11] CNN's early-vote analysis (fetched) says the Democratic skew is "far from determinative". Party registration does not show how people voted, and Republicans lately vote early in person or on Election Day. Only about 11% of the 2022 early-vote total had been cast. Mail voting was at 25% of its 2024 pace, against 72% for early in-person voting. The Democratic-looking early electorate may reflect an enthusiasm gap in who votes early rather than the final result. CNN also noted that Friday's data was slightly better for Republicans. https://www.cnn.com/2026/10/11/politics/early-voting-midterms-ohio-democratic-shift-vis
- [2026-10-12] Observers quoted by The Hill (via NewsNation and Yahoo) say preferences lean Democratic but "don't translate to votes". They say the race comes down to turnout. A Ramaswamy "nightmare scenario" is dissatisfied voters who dislike both candidates. The same observers say the Democratic brand is weaker in Ohio than the Republican brand. The Hill page itself returned 403 and was not fetched. https://www.newsnationnow.com/us-news/trump-vance-blitz-ohio-democrats-flip-governors-mansion/
- [2026-10-12] Vance (who cast an early ballot Friday in Ohio) and Trump are campaigning in Ohio. Trump is urging Republicans to vote for Ramaswamy and Husted even if they dislike them. This is a late consolidation push in a state Trump won by 11. https://www.newsnationnow.com/us-news/trump-vance-blitz-ohio-democrats-flip-governors-mansion/
- [2026-08-27] Ramaswamy's campaign had spent $25.5M and his super PAC V-PAC another $29.7M by late August (Washington Times). V-PAC and the campaign spent about $9M on ads in six weeks (May 15–end of June) while Acton spent $100K. Early definitional attacks (nursing homes, police, immigration, a 2019 police report) are why her unfavorables rose, per the Aug 13 Fox poll. An ad-spending advantage in a closing month is a plausible reason for late movement toward Ramaswamy. https://www.washingtontimes.com/news/2026/aug/27/gops-vivek-ramaswamy-spends-big-dominates-tv-attacks-tight-race-ohio/ and https://ohiocapitaljournal.com/2026/07/21/massive-spending-gap-in-ohio-governor-race-ramaswamy-drops-9m-on-ads-acton-spends-just-100k/
- [2026-10-09] The RCP table lists the Impact Research (D) poll of July 24–28 as Ramaswamy +1. Another poll, BGSU/YouGov in April, had Ramaswamy +5. Per RCP, the latest polls from Republican-aligned firms, co/efficient (+2) and Big Data (+1), show Ramaswamy ahead. The RCP average covers Sept 1–Oct 6 only and rests on a handful of polls. Several of the Acton leads (Suffolk n=500, CNN n=760, NYT n=616) have margins of error around ±4.4–4.5. https://www.realclearpolling.com/polls/governor/general/2026/ohio/ramaswamy-vs-acton
- [2026-10-10] PoliAgg's model (generated Oct 10) gives Acton 11%, with a predicted margin of R+10.5 and an 80% CI of R+21.4 to D+0.5. The same page shows a VoteHub poll average of Acton 48.0 vs Ramaswamy 45.1. Pollsmax has Acton +2.1 across 27 polls. The averages differ by source, from +2.1 to +5.5, and the smaller ones are within a normal polling miss. PoliAgg says markets are 21 points more bullish on Democrats than polling. https://poliagg.com/race/us-governor-2026-oh/ and https://www.pollsmax.com/governor/ohio/
- [2026-10-13] Status quo: Republicans have held the office since 2011. Ohio is Trump +11 (2024) and has voted straight Republican in statewide races in recent cycles. Ohio's 2018 Democratic nominee Cordray lost the open seat in a favourable midterm. No Ohio Democrat has won statewide for governor since 2006. The 2006 Strickland win came with a scandal-hit GOP, which Ramaswamy does not face. Acton's own favorability has stayed under 50% (49% Suffolk, 43% Marist, per NBC4). https://www.nbc4i.com/news/your-local-election-hq/two-polls-of-ohio-voters-show-amy-acton-ahead-of-vivek-ramaswamy-for-governor/ and https://signalohio.org/amy-acton-refuses-to-debate-vivek-ramaswamy-in-ohio-governors-race/
- [2026-09-27] NPR notes that Republicans have used a 2019 police report of a domestic disturbance at Acton's home in attacks. The Ohio GOP also circulated AI-generated images tied to it. Acton's campaign refused to debate (reported ~Sept 2), so Ramaswamy gets uncontested debate-challenge messaging ("show up") and Fox exposure. The campaign has about two weeks left to absorb this negative material. https://www.npr.org/2026/09/27/nx-s1-5976743/ohio-governors-race-ramaswamy-and-acton-clash-in-rare-democratic-pickup-opportunity
- [2026-10-13] Resolution mechanics favor no special NO path beyond the vote itself. Nothing in the rules lets a technicality produce NO other than a Ramaswamy win or a third-party or independent winner, and a Libertarian win is implausible (Kissick polls about 3%). A very close race would resolve on certification, which falls after the Nov 4 trading close. That raises the risk of a delayed or contested call, but it does not favor either side. https://www.10tv.com/article/news/politics/elections/early-voting-begins-across-ohio/530-7800500e-fd51-4100-89c1-baa54dd4f12e and https://polymarket.com/event/ohio-governor-winner-2026
BOTTOM LINE: The strongest NO case rests on structure rather than current data. Ohio is Trump +11, Republicans have held the office since 2011, polls have overstated Democrats in Ohio by 2–4 points in recent cycles, and Ramaswamy has a large money advantage. Acton's lead is within a typical polling miss, and the early-vote Democratic skew is not a vote count.
NOT FOUND: Polls dated after Oct 6, any AP, Fox or NBC call, Ohio governor-race polling-miss data for 2018 and 2022 specifically, and Ohio GOP vs Democratic split in absentee requests after Oct 11.

(0) Nothing has resolved. The election is Nov 3, 2026, and AP, Fox and NBC have not called the race (resolution-source read, Oct 13). (a) About three weeks remain until Election Day, and the result is usually called on election night or soon after. (b) Status quo: Acton (D) leads the poll averages by about 2–5 points (RCP +3.8, DDHQ +4.2, FiftyPlusOne +4.1, Pollsmax +2.1). Cook, Sabato and Inside Elections all moved the race to Toss-up, and every rating shift has been toward Democrats. The Polymarket anchor is 71.5%, up 17 points in 30 days, and Kalshi sits around 69–71%. (c) NO: Ohio's polls repeat the 2016/2018/2020/2024 pattern of understating Republicans by 2–4 points. Ramaswamy's roughly 2:1 cash-on-hand edge buys a late ad blitz, and Trump and Vance consolidate GOP voters in a Trump +11 state. The latest co/efficient (R) poll, Ramaswamy +2, could signal that tightening, and he wins narrowly. (d) YES: low Trump approval in Ohio (36–42%), Acton's edge with independents and a Democratic enthusiasm gap hold up. Brown's parallel lead points to a broad Democratic environment, so Acton wins by a few points, as in a 2006-style wave. The market looks a little rich against a lead that sits within a typical Ohio polling miss, and Ohio has a structural Republican lean and a record of Republican-favoring misses. I shade modestly below the 71.5% anchor rather than fully trusting the price.

(0) Not resolved: the election is Nov 3 and AP/Fox/NBC have made no call. (a) About three weeks remain until Election Day, with a call likely on election night or soon after. (b) Status quo: Acton leads all major averages (RCP +3.8, DDHQ +4.2, 270toWin up to +5.5, Pollsmax +2.1), and nonpartisan polls show her ahead (CNN +8, NYT/Siena +4, Marist +6, Suffolk +9). Republican-aligned polls show Ramaswamy +1 to +2. Cook, Sabato and Inside Elections all moved to Toss-up, each shift toward Democrats, and Trump's Ohio approval of 36-42% plus a Democratic enthusiasm edge back her up. The market anchor is 71.5% on Polymarket, up 17 points in 30 days, with Kalshi at about 70%. I shade slightly below it: Ohio polls have repeatedly underestimated Republicans (about 3.5 points for Trump in 2024, about 2 in the 2024 Senate race), Ohio is Trump +11, Ramaswamy has a 2:1 cash edge, and the newest poll (co/efficient) had him ahead. A +3.5 lead with a 4-5 point state polling error implies roughly 60-70%. (c) NO: late spending and Trump/Vance consolidation bring Republicans home, a 3-5 point pro-GOP polling miss recurs, and Ramaswamy wins narrowly. (d) YES: the midterm backlash holds, Acton keeps her double-digit edge with independents, and Democratic turnout carries her (and Brown) to a 2-5 point win.
