final rationale
Mean of 5 draws (0.23, 0.23, 0.22, 0.24, 0.27). (0) Nothing has resolved yet. The FEC page shows no results, and the election is November 3, 2026. (a) About 33 days remain until election day, and calling the race could take a few days more. (b) Status quo: incumbent Republican John McGuire holds an R+6 seat that Trump won by 12 points and that he won by 15 in 2024. Spanberger lost the district by 7 in 2025, and the only nonpartisan poll (WaPo/Schar, Oct 1) has McGuire up 51-45. That points to a NO resolution. (c) NO scenario: the district's partisan floor holds, McGuire's stock-trading rebuttal blunts the ethics attack, and the WaPo margin roughly holds, giving a mid-single-digit Republican hold. (d) YES scenario: a 2006-style national wave, Perriello's cash advantage, and early in-person voting running 10-11 points bluer than 2025 (State Navigate/VoteHub) push Perriello past McGuire. Perriello's internal poll (46-45) suggests the race may be close. Raters are split: Sabato moved to Leans R, Cook to Likely R, Inside Elections still has Solid R, and Nuttycombe calls it tilting R. That mix is roughly consistent with the market's 21.5%. The improving early-vote signals and favorable national environment justify a small upward nudge, but the independent 6-point poll caps it, so I land near 23%.

Planner reasoning
The Polymarket price is the main anchor. Kalshi and Polymarket markets on VA-05 and on House control give independent crowd signals for cross-venue triangulation. Wikipedia covers district background: past margins, the incumbent (John McGuire), and whether the district lines were changed by Virginia's 2026 redistricting effort. That last point is key: if VA-05 was redrawn, past results are a poor guide.

report: current state
- [2026-09-25] Cook Political Report moved VA-05 from "Solid Republican" to "Likely Republican," noting John McGuire (R) is the incumbent, Trump carried the district by 12 points in 2024, and Republican gubernatorial nominee Winsome Earle-Sears carried it by eight points , though the district's Cook PVI is R+6 — summary text notes Perriello and a super PAC are "hammering" McGuire on the airwaves and polls show a close race (https://www.cookpolitical.com/house/race/485456). - [2026-10-01] Roll Call reports an internal Perriello campaign poll (fielded Sept. 21-24) found McGuire at 46 percent and Perriello at 45 percent, with independent candidate Cooke Costa Harvey taking 6 percent and 3 percent undecided (https://rollcall.com/2026/10/01/at-the-races-debate-demands-and-dodges/). - [2026-08-04] Virginia's primary: Republican incumbent Rep. John McGuire and Democrat Tom Perriello each won their party's primary, earning spots on the November ballot , with McGuire defeating Melanie Lucero with 85.4 percent, and Perriello defeating Robert Tracinski and Suzanne Krzyzanowski with 76.7 percent (https://www.cavalierdaily.com/article/2026/08/virginia-primary-election-day-live-updates-and-results). - [2026-08-01] An Expedition Strategies poll (July 29-Aug 1, 2026) for Perriello's campaign found McGuire leading Perriello 47% to 44% on an initial ballot, within the margin of error; after positive bios the race flips to Perriello 47%-44%; after hearing McGuire's record, Perriello opens an 11-point lead, 51% to 39% (https://www.tomperriello.com/news/new-poll-perriello-moves-virginias-5th-district-into-a-toss-up-race). - [~2026-08] Following that poll, the DCCC named Perriello to "Red to Blue," putting VA-05 among the nation's most competitive seats, in a district that the GOP won by 15 points just two years ago (https://bluevirginia.us/2026/08/after-poll-finds-va05-race-a-tossup-dccc-adds-tom-perriello-to-its-coveted-red-to-blue-program/). - [2026-04-21 to 2026-04-28] Virginia's mid-decade redistricting amendment, which would have made VA-05 much friendlier to Democrats, initially passed with 51.69% of the vote, but on April 28 the Supreme Court of Virginia ruled against certification and implementation of the results ; per Virginia Mercury, the ruling was later left in place by the U.S. Supreme Court, so the race is moving forward under the current court-drawn congressional map from 2021 rather than the Democratic-favoring map (https://virginiamercury.com/voter-guides/contests/2026-general-election-5th-congressional-district/; https://en.wikipedia.org/wiki/2026_Virginia_Redistricting_Amendment). - [2026-05-08] Cook Political Report headlined this reversal as "Virginia Supreme Court Overthrows New House Map, Erasing Potential Dem Gains" (https://www.cookpolitical.com/house/race/485456). - [2026-09] Fundraising: per Blue Virginia's reporting on the campaign, Perriello has outraised McGuire for three consecutive quarters, holds nearly a three-to-one cash-on-hand advantage, and has built a grassroots operation across the district (https://bluevirginia.us/2026/08/new-poll-tom-perriello-moves-virginias-5th-district-into-a-toss-up-race/). - [2026-09-30] Cook Political's House overview piece (cited in the race page) notes a broader trend: COOK PARTISAN VOTING INDEX Last updated: Nov 17, 2025 ... R +6 for VA-05, even as other GOP-held seats nationally shift toward Democrats amid a generally favorable midterm environment for the opposition party, per Roll Call's "Nathan's notes" which state most political handicappers are currently predicting a good midterm election for Democrats, with the opposition party increasingly favored to win majorities in the House and Senate (https://rollcall.com/2026/10/01/at-the-races-debate-demands-and-dodges/). - [2026-10-01] No debate between McGuire and Perriello has been confirmed as scheduled; the same Roll Call newsletter lists several House races (not VA-05 specifically) where debates have been scrapped, but does not report a confirmed VA-05 debate date (https://rollcall.com/2026/10/01/at-the-races-debate-demands-and-dodges/). - [2026-06-16/18] Republican primary date discrepancies across sources (June 16 per Ballotpedia text vs. June 18 per another Ballotpedia page vs. August 4 per most other sources) appear to be legacy/template text; the actual, confirmed primary date — consistent across NBC, WSET, Fox5, Cavalier Daily — is August 4, 2026, and results are certified (https://ballotpedia.org/Virginia's_5th_Congressional_District_election,_2026). BOTTOM LINE: VA-05 remains a Republican-leaning seat under the restored 2021 map (Cook PVI R+6, Trump +12 in 2024) with incumbent John McGuire facing a serious, well-funded challenge from former Rep. Tom Perriello; independent public and internal polling since August has consistently shown a true toss-up/margin-of-error race, prompting Cook to downgrade the seat from "Solid R" to "Likely R" and the DCCC to add Perriello to its Red-to-Blue program, but no fundamentally new facts since late September suggest a decisive swing either way heading into the final month. NOT FOUND: No independent (non-campaign) live polling averages for VA-05 in September/October 2026 were located (only internal campaign polls from Perriello's side); no confirmed debate schedule between McGuire and Perriello; no post-September 24 public polling.
report: base rate
- [2026-09-25] Cook Political Report rates VA-05 **Likely Republican** (shifted from Solid Republican), citing that "Former Rep. Tom Perriello and a liberal super PAC are hammering GOP Rep. John McGuire on the airwaves, and polls show a close race." Cook lists the district's Cook PVI as R+6. https://www.cookpolitical.com/house/race/485456 - [2026-09-29] Sabato's Crystal Ball moved VA-05 from "Likely Republican" to "Leans Republican," noting the first signs from early voting appear strong for Democrats in this district, and at Trump +12, the district's 2024 presidential partisanship is comparable to that of many of the key Senate Toss-up states , while also noting Perriello has outraised McGuire on a candidate-to-candidate basis and gotten more outside help . https://centerforpolitics.org/crystalball/will-republicans-wake-up-as-september-ends-11-more-house-ratings-changes-towards-democrats/ - [2026-10-01] Roll Call reported an internal Perriello campaign poll (Sept. 21-24) found "McGuire at 46 percent and Perriello at 45 percent, with independent candidate Cooke Costa Harvey taking 6 percent and 3 percent undecided" — essentially a tied race, though this is a partisan internal poll. https://rollcall.com/2026/10/01/at-the-races-debate-demands-and-dodges/ - [2026-10-01] By contrast, a Washington Post/Schar School poll (reported same day) found McGuire leading Perriello 51%-45% , with the article noting analyst Chaz Nuttycombe's current thinking placing VA-05 as "tilting R" ; the Post piece noted Abigail Spanberger (D governor candidate) lost the district by 7.2 points in November 2025, so a 6-point McGuire lead is only marginally better for Democrats than that baseline . 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/ - [2026-08-18] An August Expedition Strategies poll (commissioned by Perriello's campaign) showed McGuire leading Perriello 47% to 44% on an initial ballot, within the poll's margin of error, with the race flipping to Perriello 47%-44% after voters heard positive information about both candidates , prompting the DCCC to add Perriello to its "Red to Blue" program. https://bluevirginia.us/2026/08/after-poll-finds-va05-race-a-tossup-dccc-adds-tom-perriello-to-its-coveted-red-to-blue-program/ - [2026-09-30] Newsweek summarized the national ratings shift, noting "Virginia's 5th District presents a steeper climb. It backed Trump by 12 points, yet former Representative Tom Perriello has outraised Republican John McGuire directly, while analysts cited by the Crystal Ball reported encouraging early-voting signs for Democrats." https://newsweek.com/republicans-warning-signs-seats-shift-toward-democrats-12505117 - [2026] Historical base rate: VA-05 has a Cook PVI of R+6, among the most Republican ~179th districts nationally; it was one of the first Virginia districts to turn Republican in presidential elections and has not supported a Democrat for president since Harry S. Truman in 1948 , though Democrat Tom Perriello won the seat in 2008 on Obama's coattails before losing it in 2010. https://en.wikipedia.org/wiki/Virginia's_5th_congressional_district - [2024-11-05] Most recent election: John McGuire (R) defeated Gloria Tinsley Witt (D) in the general election for U.S. House Virginia District 5 on November 5, 2024, by 57.3% to 42.3% , a 15-point GOP margin. https://ballotpedia.org/Virginia's_5th_Congressional_District_election,_2026 - [2026-08-04] Perriello, a former one-term congressman who previously won this seat in 2008 and lost it in 2010, is the 2026 Democratic nominee, having handily won a three-way Democratic primary, defeating physician Suzanne Krzyzanowski and activist [Cooke Harvey] ; he faces McGuire, who won the Republican primary, defeating challenger Melanie V. Lucero (and also fended off a Bob Good primary bid). https://www.vpm.org/elections/2026-08-05/va05-primary-results-us-house-federal-midterms/ - [2026-09-28] VPM/public media reporting frames the race as a genuine Democratic opportunity: "state and national Democrats are hoping that political backlash to President Donald Trump's agenda — and incumbent Rep. John McGuire's staunch devotion to that agenda — has made the district a winnable target in 2026." https://www.vpm.org/elections/2026-09-28/va05-harvey-mcguire-perriello-candidate-survey/ - [2026 cycle] Scandal/ethics narrative: Perriello's campaign and the DCCC have made McGuire's stock trading a central attack line, alleging "In less than one term in Congress, John McGuire has traded up to $176,000 worth of stocks, and owned stock in companies he oversees as a lawmaker, like Elon Musk's company SpaceX" ; McGuire disputes the insider-trading characterization, saying "his investments are managed through retirement accounts and that he does not direct the trades." https://dccc.org/races/va-05/ ; https://www.cbs19news.com/news/mcguire-pushes-back-on-perriello-s-insider-trading-claims/article_7ded725e-646e-49b3-94da-2d45a8fec5fa.html BOTTOM LINE: The base rate strongly favors Republicans — VA-05 is an R+6 PVI seat that Republicans have won in 7 of the last 8 cycles (with McGuire winning by 15 points in 2024), but the 2026 race is unusually competitive by historical standards, with nonpartisan raters (Cook, Sabato) downgrading the GOP's position from "Solid/Likely R" toward "Leans R" amid mixed polling (one poll shows a tie, another shows McGuire +6) and a strong, previously-successful Democratic challenger (Perriello) in a favorable national environment for Democrats. NOT FOUND: No recent (last 30 days) independent/nonpartisan poll of VA-05 beyond the WaPo/Schar poll and dueling campaign-sponsored polls; no FiveThirtyEight/Silver Bulletin-style probabilistic model estimate specific to this race; exact current Inside Elections rating (only referenced secondhand via Roll Call).
report: yes case
YES means: Democrat Tom Perriello wins the VA-05 U.S. House seat in the November 3, 2026 general election, flipping it from Republican incumbent John McGuire. - [2026-09-29] Sabato's Crystal Ball cited VoteHub/State Navigate analysts noting Virginia early in-person voting by congressional district was running "VA-5: 10-11 pts bluer than 2025," with Nelson County at 170% of its 2025 same-day-equivalent early vote and Danville—"not really Perriello's home turf"—at 129%. https://dccc.org/%F0%9F%91%80momen-tom-early-voting-could-hardly-look-better-for-perriello-in-va-05/ Now compiling the final report. REPORT: YES means: Democrat Tom Perriello defeats Republican incumbent John McGuire to win VA-05, flipping the seat from R to D. - [2026-09-29] Analyst VoteHub, cited by the DCCC, said "the low-propensity voters showing up in VA-05 are even more Democratic-leaning than the high-propensity voters," concluding early evidence put the race "closer to Tilt than Likely" Republican rather than solidly Likely R. https://dccc.org/%F0%9F%91%80momen-tom-early-voting-could-hardly-look-better-for-perriello-in-va-05/ - [2026-09-29] State Navigate's county-level tracking found VA-5's early in-person vote running "10-11 pts bluer than 2025," with Nelson County at 170% of its 2025 same-day-equivalent early vote and Danville — explicitly noted as "not really Perriello's home turf" — at 129%, suggesting Democratic enthusiasm extending beyond the candidate's base. https://dccc.org/%F0%9F%91%80momen-tom-early-voting-could-hardly-look-better-for-perriello-in-va-05/ - [2026-09-29] Sabato's Crystal Ball moved VA-05 from Likely Republican to Leans Republican, explicitly reasoning that if Democrats flip VA-5, which includes Charlottesville and Southside Virginia, it would be consistent with a 2006-style blue wave, and at Trump +12, the district's 2024 presidential partisanship is comparable to that of many of the key Senate Toss-up states , and that Perriello has outraised McGuire on a candidate-to-candidate basis and gotten more outside help, with early voting signs appearing strong for Democrats per analysts Nuttycombe and Donnini . - [2026-09-23] Local TV (WVIR) reported FEC filings show Perriello has raised more campaign money than McGuire, with Perriello raising $2.1 million over the past 19 months compared to $1.7 million for McGuire , which UVA Center for Politics analyst Miles Coleman said reflects confidence from Democratic donors who "want to give to races where they feel like their money could go far." - [2026-09-21] NPR affiliate WMRA reported that as of July 15, Perriello had raised more than $2 million with about $1.5 million cash on hand, while McGuire had raised about $1.7 million with more than half a million dollars cash on hand — giving Perriello a decisive financial edge heading into the fall stretch. - [2026-09-29] Local reporting (Lynchburg News & Advance) confirmed turnout data showing early voting in the 1st Congressional District leads the state for turnout... Turnout was next highest in the 5th District, where Rep. John McGuire, R-5th, is trying to keep his seat in a well-financed challenge by former Rep. Tom Perriello, D-5th — placing VA-05 among the two highest-turnout, most competitive districts statewide. - [2026-09-18] At a Charlottesville rally kicking off early voting, Perriello campaigned alongside Governor Spanberger and Rep. Walkinshaw; coverage noted Perriello was joined by Governor Abigail Spanberger and 11th District Congressman James Walkinshaw, as Democrats called on supporters to begin turning out at the polls, while Republican incumbent John McGuire was campaigning through a Republican tele-rally that included President Donald Trump — signaling top-of-ticket Democratic investment in the race. - [2026-09-09] Perriello's campaign launched its first TV ad attacking McGuire's ethics, stating John McGuire has taken over $187,000 in political contributions from corporations and corporate lobbyists, with the ad airing as McGuire scrambles to address accusations of trading on insider information — a sustained messaging advantage DCCC/Perriello have pressed relentlessly on McGuire's stock-trading controversy. - [2026-08-26] WSET reported Perriello has already agreed to an Oct. 20 debate hosted by ABC13/University of Lynchburg, while Perriello has agreed to debate McGuire on Oct. 20, but McGuire's office has not responded about whether he will participate — if McGuire ducks, it could reinforce a "hiding from scrutiny" narrative Democrats are already running on. - [2026-10-01] A Blue Virginia summary of the WaPo/Schar poll noted analyst Chaz Nuttycombe's real-time district rating sat at "tilting R" but flagged it could arguably be revised to "lean R," observing the poll's 6-point McGuire margin was "kind of disappointing... especially given such strong early vote numbers for the Democrats," underscoring that even skeptical Democratic-aligned analysts see the turnout data as genuinely favorable for Perriello despite a mixed horse-race poll. 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/ BOTTOM LINE: The strongest YES case rests on converging, dated signals since mid-September — a clear Perriello fundraising/cash advantage, nonpartisan raters (Cook, Crystal Ball) moving the seat toward Democrats, and early in-person turnout data (10-11 points bluer than 2025, concentrated gains even outside Perriello's base) that multiple independent trackers call unusually encouraging for a Trump+12 district — suggesting a genuine path to a 2008-style upset flip, even though it would still require Perriello to outperform both the WaPo/Schar horse-race poll and the historical partisan baseline. NOT FOUND: No non-campaign poll since the Oct. 1 WaPo/Schar survey; confirmation of whether McGuire will actually appear at the Oct. 20 debate; a finalized, cumulative (not just incremental) early-vote partisan-composition estimate specific to VA-05 analogous to VoteHub's statewide "Harris +10.4" electorate projection.
report: no case
YES means: Tom Perriello (D) defeats incumbent Rep. John McGuire (R) in VA-05 on Nov. 3, 2026, flipping the seat to the Democratic column. This dimension argues the strongest case that this does NOT happen (McGuire holds the seat, resolving NO). - [2026-10-01] The only live, non-campaign poll available — the Washington Post/Schar School survey — has McGuire leading Perriello 51%-45%, a 6-point Republican edge, not a tie; it also found Trump's net approval in VA-05 still positive-leaning relative to other swing districts and noted "several indicators show the district's more firm Republican tilt that favors McGuire." (https://politicalwire.com/2026/10/01/two-virginia-districts-shift-left) - [2026-10-01] That same Post poll's own framing undercuts the "Democratic surge" narrative: analyst Chaz Nuttycombe's current call is still "tilting R" for VA-05, even as he moved VA-01 to "tilting D," showing forecasters distinguish VA-05 as the harder lift for Democrats. (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] A direct, current-cycle benchmark: Abigail Spanberger (D) lost VA-05 by 7.2 points in the November 2025 gubernatorial race even while winning statewide — meaning the district's floor for Republicans has held up in the very latest actual Virginia election, and the new WaPo poll margin is only marginally better for Democrats than that baseline (per Blue Virginia's write-up of the poll). - [2026-09-19] Inside Elections — a third major nonpartisan handicapper distinct from Cook/Sabato — still rated VA-05 "Solid R" as of mid-September, more bullish on Republicans than either Cook's "Likely R" or Sabato's "Leans R," with one grassroots Democratic analysis calling Inside Elections "too pessimistic for Dems" on this very seat (https://www.dailykos.com/stories/2026/9/19/800100453/). - [ongoing] A separate ratings tracker (PollingSource) lists VA-05 as "Safe R" with a Cook PVI of R+12 for this cycle — a notably more Republican-friendly lean than the R+6 figure other reports cite — illustrating that not all current compilations agree the seat has become truly competitive (https://pollingsource.com/house/VA-05). - [2026-09-21] Despite Perriello's cash advantage, UVA Center for Politics analyst Kyle Kondik noted that as of that date there was no coordinated spending booked between McGuire and the NRCC, nor outside spending specifically tied to NRCC coordination in "Virginia Five" — i.e., the national GOP apparatus had not yet mobilized major reinforcements, which is consistent with internal confidence that the seat's fundamentals hold without heavy intervention (https://www.wmra.org/2026-09-21/can-money-help-overcome-challenges-for-democrats-in-the-deep-red-5th-district). - [2026-09-23] Independent reporting (WVIR/29News) confirms Perriello's fundraising lead ($2.1M to $1.7M raised) is modest in absolute terms and is similar in scale to what McGuire raised in 2024 when he still won by 15 points over a Democrat who raised a fifth as much — suggesting a cash edge alone has not historically been sufficient to flip this seat (https://www.29news.com/2026/09/23/perriello-outraises-mcguire-5th-district-race-funding/). - [historical] Perriello's only prior VA-05 win (2008) came on an Obama-wave anomaly and was reversed just two years later in a double-digit 2010 loss, the classic pattern of a red-leaning seat snapping back once the wave recedes — a precedent directly on point for whether a single favorable environment "flips" this specific seat for good. - [structural] The restored 2021 court-drawn map (confirmed by the April 28 Virginia Supreme Court ruling and left in place by SCOTUS) locks in the more Republican-favorable boundaries for 2026, removing what would have been the single biggest mechanical boost to a Democratic win this cycle. - [2026-09-23] McGuire's campaign is actively contesting the DCCC's "insider trading" attack line, stating his investments are managed through retirement accounts he does not direct — an active rebuttal rather than silence, suggesting the campaign believes it can neutralize the scandal narrative with swing voters. BOTTOM LINE: Every nonpartisan or independent (non-campaign) data point from the final weeks of September/early October — the WaPo/Schar poll, Inside Elections' "Solid R," PollingSource's "Safe R," Nuttycombe's "tilting R" call, the 2025 Spanberger-margin benchmark, and the still-R+6-to-R+12 PVI — points to McGuire remaining the favorite, with Democratic gains this cycle concentrated in other VA seats (VA-01, VA-02, VA-07) rather than VA-05, consistent with a status-quo Republican hold. NOT FOUND: No evidence of any independent poll since Sept. 24 showing Perriello ahead; no confirmed NRCC/outside-group ad buy total for VA-05 to compare against the ~$1.9M in Democratic-aligned spending already reported; no post-Oct.-1 early-vote tallies broken out by party for the district.

(0) Nothing has resolved yet. The FEC page shows no results, and the election is November 3, 2026. (a) About 33 days remain until election day, and calling the race could take a few days more. (b) Status quo: incumbent Republican John McGuire holds an R+6 seat that Trump won by 12 points and that he won by 15 in 2024. Spanberger lost the district by 7 in 2025, and the only nonpartisan poll (WaPo/Schar, Oct 1) has McGuire up 51-45. That points to a NO resolution. (c) NO scenario: the district's partisan floor holds, McGuire's stock-trading rebuttal blunts the ethics attack, and the WaPo margin roughly holds, giving a mid-single-digit Republican hold. (d) YES scenario: a 2006-style national wave, Perriello's cash advantage, and early in-person voting running 10-11 points bluer than 2025 (State Navigate/VoteHub) push Perriello past McGuire. Perriello's internal poll (46-45) suggests the race may be close. Raters are split: Sabato moved to Leans R, Cook to Likely R, Inside Elections still has Solid R, and Nuttycombe calls it tilting R. That mix is roughly consistent with the market's 21.5%. The improving early-vote signals and favorable national environment justify a small upward nudge, but the independent 6-point poll caps it, so I land near 23%.

(0) Nothing is resolved yet. The FEC page shows no results and the election is November 3, 2026, so Perriello still has to outpoll McGuire under the restored 2021 map. (a) About 33 days remain, and early voting is already underway. (b) If nothing changes, Republican incumbent McGuire holds an R+6 / Trump+12 seat. He won it by 15 points in 2024, and Spanberger lost it by 7.2 points in 2025 even while winning statewide. (c) NO: the only nonpartisan poll, WaPo/Schar showing McGuire 51-45, holds up, and the district's partisanship absorbs the national wave. Democratic gains concentrate instead in VA-01, VA-02 and VA-07, consistent with Inside Elections' 'Solid R' and Nuttycombe's 'tilting R'. (d) YES: a 2006/2008-style wave combines with Perriello's cash edge, the stock-trading attacks and early votes running 10-11 points bluer than 2025. Low-propensity Democratic turnout erases a mid-single-digit deficit, as Perriello managed in 2008. The ratings now range from Solid R to Lean R. Seats rated that way flip roughly 15-25% of the time in strong opposition-party years, and the national environment clearly favors Democrats (Jeffries 88% for next Speaker). The Polymarket anchor is 21.5%. The encouraging early-vote data is partly offset by the fresh +6 independent poll, so I nudge only slightly above the market.

(0) Nothing is resolved. The FEC page shows no results, and the election is November 3, 2026. Perriello (D) would have to beat incumbent McGuire (R) in the general. (a) About 33 days remain until the election, and the market closes November 4. (b) The status quo is a Republican hold. The seat is R+6 PVI, Trump won it by 12, McGuire won by 15 in 2024, and Spanberger lost it by 7.2 in 2025 while winning statewide. The only nonpartisan poll, WaPo/Schar on Oct 1, has McGuire up 51-45. (c) NO: the district's partisan floor holds, McGuire wins by 4-8 points, and Democratic gains land in VA-01, VA-02 and VA-07 instead. (d) YES: a 2006/2008-style wave plus Perriello's cash edge and strong early vote close the gap. Early in-person voting is running 10-11 points bluer than 2025. Combined with a typical House polling error of about 5 points against the 6-point WaPo deficit, Perriello could edge it, as he did in 2008. The market sits at 21.5%, up 6.5 points over 30 days, and the mirrored R market is at 77.5%. The raters are at Likely R (Cook) and Lean R (Sabato), with Inside Elections still at Solid R. The research adds no clear unpriced information, since the bullish early-vote data and the bearish WaPo poll roughly offset. I stay near the anchor at 22%.

(0) The resolving condition has not been met: the FEC page contains no 2026 VA-05 result, and Perriello would still need to win the November 3 election and be identified as the winner by credible reporting or official results. (a) There are about 33 days until Election Day and 34 days until the November 4 market close. (b) If the current political alignment persists, Republican incumbent John McGuire holds the seat, so the status quo outcome is No. (c) A straightforward No scenario is that McGuire retains most of the district's R+6 electorate and converts the Washington Post/Schar School poll's 51%-45% lead into a modest victory, consistent with Trump's 12-point 2024 margin and Spanberger's 7.2-point 2025 loss there. (d) A Yes scenario is that Perriello's fundraising advantage, favorable Democratic environment, ethics attacks, and unusually Democratic early-vote composition produce a wave-level upset similar to his 2008 victory. Polymarket's 21.5% Yes price is the primary anchor, while Sabato's move to Leans Republican, Cook's downgrade to Likely Republican, and strong early-voting signals justify a small upward adjustment. I limit that adjustment to 24% because the best recent independent poll still shows McGuire ahead by six, whereas the near-tie polling is campaign-sponsored and the restored 2021 map preserves the district's Republican lean.

(0) The election has not occurred and the FEC page contains no VA-05 result, so the condition is neither met nor impossible; Perriello must win the November 3 election and be identified as the winner by credible reporting or official results. (a) About 33 days remain until Election Day, with trading closing early on November 4. (b) If nothing changes, the status quo is a Republican hold and therefore No: McGuire is the incumbent, the restored district is R+6, Trump carried it by 12 points in 2024, and the latest independent Washington Post/Schar poll has McGuire ahead 51%-45%. (c) A No scenario is that the district's Republican lean persists, the favorable Democratic early-vote composition proves partly timing rather than net turnout, and McGuire wins by several points. (d) A Yes scenario is that Perriello's fundraising and cash advantage, strong Democratic early voting, anti-incumbent national environment, and attacks on McGuire produce a late wave-style upset. I anchor on Polymarket's 21.5% Yes price but move modestly upward because Sabato shifted the race to Leans Republican and the unusually favorable early-vote and fundraising evidence may not be fully priced, while keeping No clearly favored because the strongest independent poll and historical baseline still support McGuire.
