What it would take for Arthur Purves.
Walkinshaw starts 36.3 points ahead on our starting line from recent official results. Campaign work can move about 7,953 net votes toward Purves, a 2.7-point gain. Winning outright would take a 33.6-point national wave on top of that. Here is the plan that makes Purves the one standing if one comes.
A long shot on the math: it takes a 33.6-point national wave.
144,839 votes.
That is half of the 289,676 ballots we expect in this race, plus one. Where Purves stands today, and what is missing:
Starting line: a weighted blend of the official 2022, 2024 and 2025 results in this district (House, President, Governor). No 2026 polls have been published. 2026 turnout modeled on 2022, the last midterm.
0% today. A wave changes that.
We ran this race 20,000 times with realistic error on every assumption. Drag the slider to see the odds move as the campaign captures more of what history says is available.
Each simulation draws the starting line with an error of 7 points of margin (no 2026 polls, so the starting line comes from history and carries more error) and lets the plan over- or under-deliver by 30 percent. Seeded and reproducible; the method and data are at the bottom of the page.
The gap closes three ways.
Change minds. Bring out voters who skip midterms. Win back the third-party vote. Every pool below is counted from official precinct returns and published polls.
Who. 7,629 voters who split their ticket in recent elections and lean Walkinshaw today.
How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. Purves needs to win 50 percent of the ones now leaning Walkinshaw.
Who. There are almost no precincts Purves's side carries, so turnout alone cannot help here.
How. Voter ID calls to people who voted in 2024 and skipped 2022, then a ballot chase until each one has voted.
Who. Voters who went third party in recent races, in the precincts that lean Purves's way.
How. A direct appeal to voters who went third party last time. They have already shown they will leave the two-party default.
Together: 7,953 net votes against a gap of 105,230. Still 97,277 short. The rest needs a national shift of about 33.6 points that no campaign controls.
12 precincts carry 13% of it.

The hidden path.
Vienna #1 (Fairfax) carries the most.
Vienna #1 (Fairfax) gives this plan more net votes than any other precinct: 96. It sits at Walkinshaw +40 on our starting line, and 6.7 percent of its voters split their ticket in recent elections.
Franklin (Fairfax) splits its ticket the most.
Of the precincts in this plan, Franklin (Fairfax) has the highest share of ticket splitters: 7.5 percent. That is where a persuasion call is most likely to reach someone open to crossing over.
The honest math.
Every lever at its historical ceiling moves 7,953 net votes. The gap is 105,230. That is the measure of what a strong campaign adds: 2.7 points of margin, and first position if the national mood breaks.

- Now to October 4Find them
Voter ID calls across the persuasion list in these precincts. Every conversation tags the voter: with Purves, with Walkinshaw, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list.
- October 5 to 16Persuade
Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 7,629 net votes from people who have crossed party lines before.
- October 17 to 26Bank the ballots
By September 24, 17,289 ballots had already been cast in the district (8,195 in person, 9,094 by mail), and 44,498 requested mail ballots were still outstanding, per the Department of Elections early voting file. Chase every supporter's mail ballot request until it is returned, and move supporters to early voting while it is open.
- October 27 to 31Turn them out
The drop-off voters: people who voted in 2024 and skipped 2022. At least 0 of them live where Purves is favored. In-person early voting ends Saturday, October 31 at 5 p.m. Mail ballots count if postmarked by November 3 and received by noon on November 6.
- November 3Election day
Polls are open 6 a.m. to 7 p.m. Virginia allows same-day registration with a provisional ballot. The last calls go to identified supporters who have not voted, with their polling place in hand.
No wishful thinking.
Official results in this district: the Democratic nominee carried the 2024 House race by 33.8 points; Harris carried the 2024 presidential race by 34.0 points; Spanberger carried the 2025 governor's race by 47.3 points.
- Purves wins 50 percent of the ticket splitters now leaning Walkinshaw.
- The national environment moves about 33.6 points toward Purves's side between now and November 3.
- No 2026 public poll exists for this race, so the starting line is a weighted blend of official recent results; the first real poll will move it.
1,755 conversations.
That is how many live voter conversations this plan takes: about 33,499 dials to 11,166 households, before the last ballot is cast.
Call list: every ticket splitter and undecided voter in the targeted places (you cannot tell which way they lean before the call), every targeted drop-off voter, and the reachable third-party voters. About 69 households for every 100 voters on the list, three attempts each, and a 5.24 percent live answer rate per attempt, the per-program average across 1.2 million real 2026 dials in our published benchmarks.
We run this list.
Calls are the voter ID and ballot chase engine of this plan. They find the persuadable voters and the supporters, so every other dollar lands on the right door. The full call program for this list is an estimated $4,982 at our published rates: 11,166 households, three attempts each.
Professional live callers working exactly these precincts: persuasion on the ticket splitters, voter ID on the fence, ballot chase on every absentee request until it is returned. A live dashboard shows every conversation as it happens. Days to launch, not weeks.
