final rationale
Mean of 4 draws (0.26, 0.27, 0.25, 0.25). (0) Nothing has resolved. The FEC shows no 2026 results, and the general election is on Nov 3, 2026. (a) About 3.5 weeks remain. Early voting is already underway and runs through Oct 31. (b) Status quo favors the Republican incumbent, John McGuire. The latest nonpartisan poll (WaPo-Schar, Sept 23–28) has him up 51-45. The district is R+6; Trump carried it by 12 and McGuire won by 15 in 2024. Cook rates it Likely R, Inside Elections Likely R and Sabato Lean R. (c) NO: the structural lean holds, McGuire's roughly 6-point edge survives, and Perriello lands around 47-48%, as Kondik's base case suggests. (d) YES: a strong Democratic environment (the Kalshi market prices Jeffries as next Speaker at 85%), plus early-vote enthusiasm about 4 points more Democratic than 2025, a fundraising and outside-spending edge, and McGuire's insider-trading story, let a well-known former member close a gap within about 1.5x the poll's margin of error. A district poll miss of this size is common. The Polymarket anchor is 25.5% and trending up (+11 over 30 days), which already prices the rating shifts and the poll. I see no unpriced information strong enough to move materially, so I sit at the market with a slight nod to the momentum.

Planner reasoning
The Polymarket price is the main anchor, and the FEC page is where the market resolves. Kalshi and related Polymarket House markets give independent cross-market prices. Wikipedia supplies the district's partisan lean, past margins (the incumbent is John McGuire), and the 2026 candidate field. This matters given Virginia's mid-decade redistricting effort.

report: current state
- [2026-08-04] Tom Perriello (D), a former one-term congressman (2009–2011) who was Biden's U.S. Special Envoy for Sudan, won a three-way Democratic primary (defeating Suzanne Krzyzanowski and Robert Tracinski) to be the Democratic nominee for VA-05; incumbent Rep. John McGuire (R) won the Republican primary over Melanie Lucero and Bob Good the same day. Republican Congressman John McGuire will defend his 5th District seat in the general election against former Congressman Tom Perriello. Perriello handily won a three-way Democratic race, defeating physician Suzanne Krzyzanowski and activist Robert Tracinski. (https://www.vpm.org/elections/2026-08-04/va05-primary-results-us-house-federal-midterms) - [2026-05-08] The Virginia Supreme Court struck down a Democratic-backed redistricting amendment in a 4-3 ruling, meaning the 2026 election uses the pre-existing (2021 court-drawn) map rather than a Democratic-favorable map that could have flipped the seat. The high court found that the amendment itself was flawed because lawmakers approved the proposal after voting had already started in the 2025 House of Delegates elections...The 4-3 ruling leaves the state's current congressional districts — which give Democrats a 6-5 advantage — in place throughout the 2026 midterm election and the rest of the decade. (https://virginiamercury.com/2026/05/08/supreme-court-of-virginia-strikes-down-redistricting-amendment-keeps-current-maps-in-place/) - [2026-05-15] The U.S. Supreme Court declined to intervene, leaving the Virginia ruling in place, so VA-05 remains the current R-leaning (Cook PVI R+6) district rather than a redrawn Democratic-friendly one. The Supreme Court on Friday turned down a request by Virginia's attorney general and other Virginia Democrats to allow the state to use a new congressional map, which would have been expected to strongly favor Democrats, in the 2026 elections. (https://www.scotusblog.com/2026/05/court-denies-virginias-request-to-reinstate-congressional-map-that-would-benefit-democrats/) - [2026-10-01] A Washington Post–George Mason Schar School poll (conducted Sept. 23–28, margin of error 4.5–4.6 points) found McGuire leading Perriello 51%–45% among likely voters, a tightening from his 15-point 2024 win. A new Washington Post-Schar School poll released Thursday shows McGuire leading Perriello 51% to 45% among likely voters. The poll has a margin of error of 4.5 to 4.6 percentage points. McGuire won his first term in 2024 by 15 percentage points. (https://wset.com/news/local/5th-district-race-tightens-ahead-of-election-day-according-to-new-poll-september-2026-tom-perriello-john-mcguire-politics) - [2026-10-06] The poll's internal crosstabs showed Perriello doing well in Charlottesville/college areas while McGuire leads the more conservative rural/exurban parts of the district; Perriello's campaign claims he is within 1 point including independent Cooke Harvey, who wasn't in the WaPo survey. Independent candidate Cooke Costa Harvey is also on the ballot and may peel votes away from the major party candidates. "The Washington Post polling didn't include the independent candidate [in its survey]," Perriello campaign manager Lily Franklin told the Daily Signal. "Tom is within one point in our internal polling, which includes the independent." (https://www.dailysignal.com/2026/10/06/poll-two-virginia-congressional-districts/) - [2026-10-04/05] Perriello is actively campaigning, holding a rally in Charlottesville on Oct. 2 where he framed the race around affordability and positioned it as a potential "first election of the post-Trump era"; McGuire has leaned heavily on a Trump endorsement and his record. McGuire, among the most conservative members of Congress, has been endorsed by President Donald Trump in his run for another term. (https://www.dailysignal.com/2026/10/04/democrat-challenger-tom-perriello-stumps-in-virginias-5th-district/; https://virginiamercury.com/voter-guides/contests/2026-general-election-5th-congressional-district/) - [2026-10-01] Early voting is underway (began Sept. 18, runs through Oct. 31), and VA-05 is reported as the second-busiest district in Virginia for early voting, trailing only VA-01. According to an analysis by the nonpartisan Virginia Public Access Project, the Perriello-McGuire race is currently the second-busiest congressional district in Virginia for early voting, behind the 1st District race between Republican incumbent Rob Wittman and Democrat Shannon Taylor. Early voting began Sept. 18 and continues through Oct. 31. (https://wset.com/news/local/5th-district-race-tightens-ahead-of-election-day-according-to-new-poll-september-2026-tom-perriello-john-mcguire-politics) - [2026-09-28] A VPM candidate questionnaire (updated Oct. 1) notes McGuire declined to respond to the survey while Perriello and independent Cooke Harvey answered; it underscores that only one Democrat (Perriello) has represented VA-05 since 2000, and Democrats view 2026 as a potential opening due to backlash against Trump's agenda. Only one Democrat — Tom Perriello, who is on the ballot this fall — has represented the 5th in Washington since then-Rep. Virgil Goode left the party ahead of the 2000 election. (https://www.vpm.org/elections/2026-09-28/va05-harvey-mcguire-perriello-candidate-survey/) - [2026-07-23] Perriello substantially outraised McGuire in fundraising, reporting $1.5 million on hand versus McGuire's $524,000 as of that date. Despite the obstacles in the district and its electoral history, Perriello has more campaign funds than McGuire: $1.5 million to McGuire's $524,000, as of July 23. (https://www.vpm.org/elections/2026-08-04/va05-primary-results-us-house-federal-midterms) - [2026-10-05] Virginia Mercury notes Perriello is attempting to "repeat the upset" from 2008 when he beat a Republican incumbent, but that Trump carried the district by 12 points in 2024 and McGuire beat Gloria Witt 57.3%–42.3% that year, underscoring the district's structural GOP lean. President Donald Trump carried the district by about 12% in 2024. That year, McGuire defeated Democrat Gloria Witt 57.3% to 42.3%. (https://virginiamercury.com/2026/10/05/perriello-seeks-another-5th-district-upset-as-mcguire-leans-on-trump/ — via search snippet; direct fetch failed) - [as of Feb 2026, last Ballotpedia update found] Major outlet race ratings (Cook Political Report, Inside Elections, Sabato's Crystal Ball) rated VA-05 "Solid/Safe Republican," though these ratings predate the September-October tightening shown in the WaPo/Schar poll and may not reflect the most recent tightening. NOT FOUND: any race-rating update (Cook/Inside Elections/Sabato) from September or October 2026 reflecting the closer polling. - [2026-11-03] Election day itself has not yet occurred; the seat's outcome remains undecided as of this report's writing (Oct. 10, 2026). BOTTOM LINE: VA-05 remains on the pre-2021 court-drawn, Republican-leaning map (Trump +12 in 2024, Cook PVI R+6) after Democrats' redistricting push was blocked by courts, and incumbent Republican John McGuire leads Democrat Tom Perriello 51%-45% in the most recent (late Sept./early Oct. 2026) nonpartisan poll, though Perriello has more cash on hand and the race is visibly tightening with heavy early-voting activity. NOT FOUND: Updated professional race ratings (Cook/Sabato/Inside Elections) from after the late-September WaPo-Schar poll; any newer poll after Oct. 6, 2026; official FEC-certified results (not yet available, election is Nov. 3, 2026).
report: base rate
- [2026-09-25] Cook Political Report shifted VA-05 from "Solid R" to "Likely R" — the only ratings movement toward Democrats among its four ratings lines since Jan. 2026 (previously Solid R from Cook, Inside Elections, and Safe R from Sabato's Crystal Ball across Jan–Feb 2026 snapshots). Tom Perriello and a liberal super PAC are hammering GOP Rep. John McGuire on the airwaves, and polls show a close race. We're shifting this from Solid to Likely Republican. https://www.cookpolitical.com/house/race/485456 - [2026-09-25] As of that same update, Ballotpedia's tracker shows the other three outlets (Inside Elections, Sabato's Crystal Ball, DDHQ/Hill) still rating VA-05 "Solid/Safe Republican" as of their most recent snapshots in the 1/20–2/10/2026 window shown. https://ballotpedia.org/Virginia's_5th_Congressional_District_election,_2026 - [2026-10-10 (page metadata)] District's Cook Partisan Voting Index is R+6, meaning in the 2024 and 2020 presidential elections this district's results were 6 percentage points more Republican than the national average, making it the 179th most Republican district nationally. https://ballotpedia.org/Virginia's_5th_Congressional_District_election,_2026 - [2026-10-01] A Washington Post-Schar School poll (released Oct 1) shows McGuire leading Perriello 51% to 45% among likely voters, with a margin of error of 4.5 to 4.6 percentage points. https://wset.com/news/local/5th-district-race-tightens-ahead-of-election-day-according-to-new-poll-september-2026-tom-perriello-john-mcguire-politics - [2026-10-01] Context on district lean: McGuire won his first term in 2024 by 15 percentage points, and President Donald Trump also carried the district by 12 points that year. https://wset.com/news/local/5th-district-race-tightens-ahead-of-election-day-according-to-new-poll-september-2026-tom-perriello-john-mcguire-politics - [2026-10-01] Virginia Mercury notes Perriello is a credible threat: it has long been a stronghold for Republicans, but Perriello represents a formidable challenger for McGuire, as the lone Democrat to hold the seat in the past 20 years; The Cook Political Report shifted the district's rating from "Solid R" to "Likely R" in late September. https://virginiamercury.com/2026/10/01/heres-how-incumbents-in-virginias-1st-2nd-and-5th-congressional-districts-have-voted-on-abortion/ - [2024-11-25] Historical base rate for House incumbents generally: Congressional incumbents were re-elected at a 98% clip in the 2024 cycle, the same rate as in 2022 and slightly higher than the 96% rate in 2020. https://news.ballotpedia.org/2024/11/25/95-of-incumbents-won-re-election/ - [2009 (study)] Long-run academic base rate: the probability that an incumbent in the U.S. House of Representatives is reelected has risen dramatically over the last half-century; it now stands at nearly 95%. https://www.journals.uchicago.edu/doi/abs/10.1017/S0022381609090483 - [n/a] District's recent one-term pattern cuts against pure incumbent-safety base rate: the seat has changed hands/had one-term members repeatedly (Garrett, Riggleman each one term; Good lost a GOP primary in 2024), making it more competitive than a "typical" incumbent-held seat despite its R lean. https://en.wikipedia.org/wiki/Virginia%27s_5th_congressional_district - [2026-10-01] Early-voting intensity signals high engagement: the Perriello-McGuire race is currently the second-busiest congressional district in Virginia for early voting, behind the 1st District race between Republican incumbent Rob Wittman and Democrat Shannon Taylor. https://wset.com/news/local/5th-district-race-tightens-ahead-of-election-day-according-to-new-poll-september-2026-tom-perriello-john-mcguire-politics - [2026 (various dates)] Ballotpedia/Cook show candidate finance disparity favoring the Democrat: Perriello's 2025 filings showed $712,825 raised vs. McGuire's $466,130 (mid-2025 report), a financial edge consistent with "well-funded challenger" scenarios that historically improve (but rarely flip) safe-leaning incumbent districts. https://ballotpedia.org/Virginia's_5th_Congressional_District_election,_2026 BOTTOM LINE: The generic outside view for House incumbents (95-98% historical re-election rate) and this district's R+6 lean/15-point 2024 GOP margin both favor McGuire, but VA-05's own recent history of one-term members and the sole rating agency (Cook) downgrade from "Solid R" to "Likely R" amid a well-funded Democratic challenger and a tightening poll (51-45) suggest a meaningfully above-baseline, though still minority, chance of a Democratic upset relative to a typical "safe" incumbent seat. NOT FOUND: No direct FiveThirtyEight/Silver Bulletin or betting-market (other than Polymarket itself, excluded) probability estimate specifically for VA-05 was located; no FEC-certified final vote data exists yet as the election has not occurred.
report: yes case
YES means: Democrat Tom Perriello wins the VA-05 House seat in the November 3, 2026 general election, defeating Republican incumbent John McGuire (and independent Cooke Harvey). - [2026-10-01] After the Sept. 23–28 WaPo-Schar poll, Sabato's Crystal Ball moved VA-05 from "Likely Republican" to "Leans Republican," one of three Virginia districts shifted toward Democrats that week, while Sabato's Crystal Ball moved the 1st District from "leans Republican" to "toss-up" and the 2nd District from "toss-up" to "leans Democratic" alongside the VA-05 shift. (https://cardinalnews.org/2026/10/02/early-voting-numbers-show-a-shift-toward-democrats-if-those-hold-at-least-two-house-seats-in-virginia-could-flip-and-a-third-could-be-close/) - [2026-09-25] Cook Political Report moved VA-05 toward Democrats, writing that "Democrats have a significant spending advantage right now; Perriello has spent over half a million on ads, per AdImpact, and a liberal outside group called Our Virginia has spent another $900,000 on attack ads against McGuire." (https://dccc.org/🚨-ratings-change-cook-political-report-shifts-va-05-in-democrats-direction/) - [2026-10-01] Inside Elections also downgraded Republican odds, moving VA-05 from "Safe R" to "Likely R" the same week, with an analyst quoted saying "early voting could hardly look better for Perriello" . (https://dccc.org/🚨-ratings-change-inside-elections-shifts-va-05-in-tom-perriellos-direction/) - [2026-10-02] Trump-aligned PACs have begun spending defensively in VA-05, which Cardinal News calls a surprise sign of GOP concern: the piece reports two of President Donald Trump's political action committees have now put money into all three districts , something it says they "wouldn't be doing...if it didn't think it needed to defend those seats." (https://cardinalnews.org/2026/10/02/early-voting-numbers-show-a-shift-toward-democrats-if-those-hold-at-least-two-house-seats-in-virginia-could-flip-and-a-third-could-be-close/) - [2026-10-02] District-level early-vote data analyzed through early October shows Democratic-leaning localities banking more votes than in 2025 while GOP strongholds lag: Fairfax County's early vote is "up 32.3%" year-over-year while heavily Republican Scott County's is "down 52.1%," and statewide, State Navigate estimates early voting running "4.2 percentage points more Democratic than a year ago" (a strong Democratic year). (https://cardinalnews.org/2026/10/02/early-voting-numbers-show-a-shift-toward-democrats-if-those-hold-at-least-two-house-seats-in-virginia-could-flip-and-a-third-could-be-close/) - [2026-10-06] Daily Kos canvassing network Hope Springs independently moved VA-05 from "Likely Republican" to "Leans Republican," citing that "the first signs from early voting appear strong for Democrats in this district, per shrewd analysts Chaz Nuttycombe and Zachary Donnini. We are moving VA-5 from Likely Republican to Leans Republican." (https://www.dailykos.com/stories/2026/10/6/800107691/community/virginia-notes/) - [2026-10-06] Perriello has overtaken McGuire in total cycle fundraising, having brought in $2.14 million to McGuire's $1.74 million, an advantage the Daily Signal calls "a different sort of poll" that can indicate which way a race will swing. (https://www.dailysignal.com/2026/10/06/poll-two-virginia-congressional-districts/) - [2026-10-01] CNN's analysis of statewide early-voting data found a broad Democratic enthusiasm edge: localities that backed Harris by 20+ points are voting at 78% of 2024 pace versus just 61% for strong-Trump areas, and "Democratic primary participants outnumber Republican primary participants by 15 points among votes cast so far in the 1st District and 18 points in the 2nd District" — both neighboring, similarly contested VA districts, suggesting a comparable dynamic could be helping Perriello. (https://www.cnn.com/2026/10/01/politics/cnn-early-voting-takeaways-democratic-advantage) - [2026-10-05] Democratic-aligned outside groups (not just the campaign) have spent nearly $1 million against McGuire via "Our Virginia," per a local NPR affiliate's reporting that "two organizations have collectively spent more than one million dollars opposing Representative McGuire," including "Another PAC, Our Virginia, has spent nearly one million dollars on mail, digital, and broadcast media." (https://www.wmra.org/2026-09-21/can-money-help-overcome-challenges-for-democrats-in-the-deep-red-5th-district) - [2026-10-06] The WaPo-Schar poll's internal data shows McGuire's 2024 incumbent strength eroding: he won by 15 points in 2024, and the campaign's own analysts note Perriello's internal polling (including independent candidate Cooke Harvey) puts him within one point, which Perriello's manager frames as evidence of "progress...in a district that McGuire won by 15 points in 2024." (https://www.dailysignal.com/2026/10/06/poll-two-virginia-congressional-districts/) - [2026-10-05] McGuire faces an added liability narrative: a Perriello campaign ad highlights that the ad "airs as Rep. John McGuire scrambles to address accusations of trading on insider information, based on the public disclosures released by his office," a potential late-race drag on the incumbent. (https://bluevirginia.us/2026/09/video-va05-democratic-nominee-tom-perriello-launches-first-tv-ad-targets-corruption-and-rising-cost-of-rep-john-mcguire-r-va05/) BOTTOM LINE: The strongest YES case rests on a documented, multi-source trendline — three independent, non-partisan forecasters (Cook, Inside Elections, Sabato) all moved VA-05 toward Democrats in the Sept. 25–Oct. 8 window, Perriello now leads in total fundraising with heavy outside-group spending, Trump-aligned PACs felt compelled to intervene defensively, and early-voting data show a real (if modest, ~4-point) Democratic shift versus 2025 — together suggesting the "closer than expected" race could plausibly tip to Perriello if the Democratic enthusiasm/turnout edge seen statewide materializes fully in VA-05 on Election Day. NOT FOUND: No poll released after Oct. 6, 2026 showing the race within the WaPo-Schar margin of error for McGuire; no district-specific (VA-05 only) early-vote partisan tabulation beyond the statewide/county-level estimates cited; no confirmation that national Democratic enthusiasm in the early vote (strong in VA-01/VA-02) is replicated at comparable magnitude specifically within VA-05's precincts beyond the Fairfax/Scott County anecdote (VA-05 doesn't include Fairfax).
report: no case
YES means: Tom Perriello (D) is the candidate credibly reported as having won the VA-05 U.S. House seat once all 2026 House races are conclusively called, and the Democratic Party retains or flips the seat. This dimension argues the strongest case for NO (McGuire/R retains the seat). - [2026-10-10] Cook Political Report's official race page still rates VA-05 "Likely R" (upgraded from "Solid R" on 2026-09-25) — not a toss-up — and McGuire's listed last general-election result was 57.5%, underscoring that even the more bullish outside rater for Democrats still favors the Republican incumbent. (https://www.cookpolitical.com/house/race/485456) - [2026-09-21] University of Virginia Center for Politics analyst Kyle Kondik noted that as of mid/late September "there is not any outside spending booked in Virginia Five, nor has there been any coordinated spending" from NRCC or DCCC-aligned groups, and that Perriello could still fall short "48, 49% of the vote... those last few points are always hard" — a seasoned forecaster's own base case is a narrow Perriello loss. (https://www.wmra.org/2026-09-21/can-money-help-overcome-challenges-for-democrats-in-the-deep-red-5th-district) - [2026-10-08] University of Lynchburg political scientist David Richards said after the WaPo/Schar poll that "the numbers are still on McGuire's side, and Perriello has a huge climb still," while noting McGuire's bigger risk is depressed GOP turnout rather than persuasion losses — i.e., the most likely path to a Dem win is differential turnout, not a true shift in support. (https://kenbridgevictoriadispatch.com/2026/10/08/three-seek-5th-district-seat/) - [2026-10-01] The same WaPo-Schar poll crosstabs show the district's underlying structural Republican lean intact: 54% of likely voters want Republicans to control Congress and 57% hold an unfavorable view of the Democratic Party in VA-05, versus 46% unfavorable toward the GOP. (https://bluevirginia.us/2026/10/new-wapo-schar-poll-has-shannon-taylor-d-up-50-46-over-rep-rob-wittman-r-va01-rep-john-mcguire-r-va05-up-51-45-over-tom-perriello-d/) - [2026-10-01] A Democratic-leaning commentator on the same poll conceded disappointment: VA-05 Democratic gubernatorial candidate "Abigail Spanberger lost that district by 7.2 points last November," so McGuire's 51-45 lead is barely better than that losing Democratic baseline despite national headwinds against the GOP. (https://bluevirginia.us/2026/10/new-wapo-schar-poll-has-shannon-taylor-d-up-50-46-over-rep-rob-wittman-r-va01-rep-john-mcguire-r-va05-up-51-45-over-tom-perriello-d/) - [2026-09-23] Even with heavy Democratic fundraising ($2.1M vs McGuire's $1.7M over the cycle), UVA's Miles Coleman cautioned fundraising "can buy...commercials and yard signs, but it's a long way from closing the deal with the historically Republican 5th District," explicitly framing money as insufficient against structural lean. (https://www.29news.com/2026/09/23/perriello-outraises-mcguire-5th-district-race-funding/) - [2026-10-06] An independent candidate, Cooke Costa Harvey, remains on the ballot and "may peel votes away from the major party candidates," a wildcard that — absent clear evidence Harvey draws disproportionately from McGuire — creates additional downside risk to Perriello's narrow-majority path rather than guaranteed upside. (https://www.dailysignal.com/2026/10/06/poll-two-virginia-congressional-districts/) - [2026-05-08/05-15] The redistricting counterfactual that could have flipped VA-05 was foreclosed months ago: Virginia's Supreme Court voided the Democratic-favorable map and the U.S. Supreme Court declined to intervene, locking in the R+6 map for 2026 — removing the single clearest mechanism that would have made a Democratic win near-certain. - [2026-08-21] Even the DCCC's own framing when adding VA-05 to "Red to Blue" relied on "Democrats' consistent overperformance in special elections" as its evidential basis for optimism, rather than any district-specific polling lead — a rhetorical tell that national committees see this as a stretch/opportunity target, not a lean-Democratic seat. (https://cardinalnews.org/2026/08/21/notes-from-the-square-dccc-triples-down-on-its-push-to-flip-the-5th-congressional-district/) - [2024 cycle precedent] This exact seat has never elected a Democrat since Perriello himself lost it in 2010 (one term, 2009–2011); McGuire currently holds it after winning by 15 points in 2024 in a seat Trump carried by 12 points that same year, the steepest hill of any Virginia seat Democrats are targeting in 2026. BOTTOM LINE: Every current, dated data point — Cook's "Likely R" (not toss-up) rating, the Oct. 1 WaPo/Schar 51-45 McGuire lead, unfavorable district-wide partisan attitudes, and analysts' own caveats that money and enthusiasm have not yet closed the gap in a seat Democrats lost by double digits as recently as 2024 — supports McGuire's reelection and a NO resolution, with the Democrats' chance resting almost entirely on a turnout-driven overperformance rather than demonstrated vote-switching. NOT FOUND: Any poll conducted after Oct. 6, 2026 or a race-rating update later than Cook's Sept. 25 "Likely R" move (e.g., no subsequent shift to "Toss-up" by Cook, Sabato, or Inside Elections as of Oct. 10); confirmed independent-expenditure/outside-group ad-buy totals in VA-05 for October; and any FEC Q3 (July–Sept 2026) filing summary for either campaign.

(0) Nothing has resolved. The FEC shows no 2026 results, and the general election is on Nov 3, 2026. (a) About 3.5 weeks remain. Early voting is already underway and runs through Oct 31. (b) Status quo favors the Republican incumbent, John McGuire. The latest nonpartisan poll (WaPo-Schar, Sept 23–28) has him up 51-45. The district is R+6; Trump carried it by 12 and McGuire won by 15 in 2024. Cook rates it Likely R, Inside Elections Likely R and Sabato Lean R. (c) NO: the structural lean holds, McGuire's roughly 6-point edge survives, and Perriello lands around 47-48%, as Kondik's base case suggests. (d) YES: a strong Democratic environment (the Kalshi market prices Jeffries as next Speaker at 85%), plus early-vote enthusiasm about 4 points more Democratic than 2025, a fundraising and outside-spending edge, and McGuire's insider-trading story, let a well-known former member close a gap within about 1.5x the poll's margin of error. A district poll miss of this size is common. The Polymarket anchor is 25.5% and trending up (+11 over 30 days), which already prices the rating shifts and the poll. I see no unpriced information strong enough to move materially, so I sit at the market with a slight nod to the momentum.

(0) Not resolved. The FEC shows no results because the general election is on Nov 3, 2026, and no source shows the outcome determined. (a) About 24 days remain until Election Day, and resolution follows once credible outlets call the race. (b) Status quo favors the Republican incumbent, John McGuire. The seat is R+6 and voted Trump +12 in 2024; McGuire won by 15 that year, and Spanberger lost the district by 7 in her otherwise strong 2025 statewide win. The only nonpartisan poll (WaPo-Schar, Sept 23–28) has McGuire up 51-45. Cook rates it Likely R; Sabato's Leans R and Inside Elections' Likely R come from one cited source each, not verified directly. (c) NO: GOP partisanship holds in rural Southside and McGuire keeps a 3-6 point edge despite the Democratic environment, as the analysts quoted expect. (d) YES: a strong national Democratic wave plus a turnout gap (early vote reportedly running about 4 points more Democratic than 2025 statewide, heavy VA-05 early voting) and Perriello's money advantage close the last few points. The independent Cooke Harvey could also split the conservative vote. The Polymarket anchor is 25.5%, up 11 points in 30 days, which matches the documented rating shifts toward Democrats. That price is consistent with a Lean/Likely R race where the underdog trails by about 6 in a favorable national environment. I nudge slightly above market for continuing momentum and the Democratic national wave suggested by related markets, but there is no new unpriced information to justify a larger move.

(0) Not resolved. FEC.gov shows no 2026 general-election results, and the election is on Nov 3, 2026, so nothing is met or foreclosed yet. (a) About 24 days remain until the election, with the call and resolution shortly after. (b) Status quo favors NO. Incumbent McGuire (R) leads 51-45 in the only nonpartisan poll (WaPo-Schar, Sept 23-28), the district is R+6 (Trump +12 in 2024), and the redistricting that might have flipped it was struck down. (c) NO: GOP turnout holds up in rural Southside, and McGuire wins by 3-8 points, as forecasters like Kondik expect Perriello to stall near 48-49%. (d) YES: a strong Democratic national environment (Jeffries-for-speaker markets ~85%), Perriello's money edge, ~$1M in outside spending, and early-vote enthusiasm showing a ~4-point Democratic shift could combine with depressed GOP turnout to erase a 6-point gap; House polling error of that size is not unusual. Ratings drifting toward Democrats (Cook to Likely R; Sabato and Inside Elections reportedly shifting) and Trump PACs spending defensively are consistent with the market's recent rise to 25.5%, which I see as fair. Nothing in the research has clearly gone unpriced, so I stay at the anchor.
