What it would take for Victoria Broderick.
DesJarlais starts 23.9 points ahead on our starting line from recent official results. Campaign work can move about 4,389 net votes toward Broderick, a 2.7-point gain. Winning outright would take a 21.3-point national wave on top of that. Here is the plan that makes Broderick the one standing if one comes.
A long shot on the math: it takes a 21.3-point national wave.
82,783 votes.
That is half of the 165,565 ballots we expect in this race, plus one. Where Broderick stands today, and what is missing:
Starting line: a weighted blend of the official 2022 and 2024 results in this district (President and U.S. Senate in 2024, Governor in 2022). No 2026 polls have been published. 2026 turnout modeled on 2022, the last midterm.
<1% 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. 704 voters who split their ticket in recent elections and lean DesJarlais today.
How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. Broderick needs to win 50 percent of the ones now leaning DesJarlais.
Who. At least 31,340 people who voted in 2024 but not in 2022, in precincts where Broderick's side wins at least 55 percent.
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 Broderick'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: 4,389 net votes against a gap of 39,601. Still 35,212 short. The rest needs a national shift of about 21.3 points that no campaign controls.
12 precincts carry 43% of it.

The hidden path.
Precinct 08-1 (Davidson County) carries the most.
Precinct 08-1 (Davidson County) gives this plan more net votes than any other precinct: 293. It sits at Broderick +41 on our starting line, and 0.1 percent of its voters split their ticket in recent elections.
Precinct 32-3 (Davidson County) is a turnout target.
Broderick's side leads Precinct 32-3 (Davidson County) by about 55 points on our starting line, and it cast about 1,221 more ballots in 2024 than in 2022 (an estimate). Roughly that many of its 2024 voters sat out the last midterm; bringing enough of them back nets 225 votes there.
Precinct 31-4 (Davidson County) splits its ticket the most.
Of the precincts in this plan, Precinct 31-4 (Davidson County) has the highest share of ticket splitters: 2.2 percent. That is where a persuasion call is most likely to reach someone open to crossing over.
Spend it where it counts.
As of July 17, 2026, DesJarlais had $495K in cash on hand to Broderick's $8,490. That is exactly why the plan ranks every place by net votes and spends in that order instead of across the whole map.
Where voters cross over.
Every dot is a precinct. If no one split a ticket, every dot would sit on the line. The orange ones are where Broderick's side lost voters it won further up the ballot.

Voting starts October 14.
- Now to October 5Find them
Voter ID calls across the persuasion list in these precincts. Every conversation tags the voter: with Broderick, with DesJarlais, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list.
- October 6 to 13Persuade
Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 704 net votes from people who have crossed party lines before. Every supporter it finds goes straight onto the ballot chase.
- October 14 to 29Bank the ballots
Early voting runs October 14 through October 29 at county election commissions and satellite sites, with no excuse needed. Voting by mail requires an excuse, such as being 60 or older, and mailed ballots must arrive by the close of polls on November 3. Chase every supporter's mail ballot until it is returned, and move supporters to early voting while it is open. Requests must be received by October 24.
- October 30 to November 2Turn them out
The drop-off voters: people who voted in 2024 and skipped 2022. At least 31,340 of them live where Broderick is favored. Mailed absentee ballots must reach the county election commission by the close of polls on November 3; there is no postmark grace period and they cannot be dropped off by hand.
- November 3Election day
Polls close at 7 p.m. Central and 8 p.m. Eastern, and photo ID is required. Tennessee has no same-day registration; the deadline is October 5. 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: Trump carried the 2024 presidential race by 23.9 points; Blackburn carried the 2024 U.S. Senate race by 22.4 points; Lee carried the 2022 governor's race by 25.2 points.
- Broderick wins 50 percent of the ticket splitters now leaning DesJarlais.
- In Precinct 08-1 (Davidson County) and Precinct 32-3 (Davidson County), 35 percent of the people who voted in 2024 but skipped 2022 come back and vote.
- It would take a national shift of about 21.3 points toward Broderick's side, larger than any midterm swing in recent memory.
- 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.
3,697 conversations.
That is how many live voter conversations this plan takes: about 70,556 dials to 23,519 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 $8,156 at our published rates: 23,519 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.
