The plan on this page sits at 57%. Median outcome at this setting: Stout by 395.

Each simulation draws the starting line with an error of 5 points of margin (the starting line comes from 2026 polls) 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.

Three moves

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.

Persuade
8,858
net votes in the plan, from a pool of 15,546

Who. Ticket splitters and the 10 percent still undecided in the latest poll: 15,546 leaning Herrera today.

How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. Stout needs to win 28 percent of the ones now leaning Herrera.

Mobilize
1,367
net votes in the plan, from a pool of 35,129

Who. At least 35,129 people who voted in 2024 but not in 2022, in precincts where Stout'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.

Consolidate
478
net votes in the plan, from a pool of 2,398

Who. Voters who went third party in recent races, in the precincts that lean Stout'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: 10,703 net votes against a gap of 10,194. That is a win.

What the numbers say that the polls do not

The hidden path.

Precinct 2154 (Bexar County) carries the most.

Precinct 2154 (Bexar County) gives this plan more net votes than any other precinct: 219. It sits at Stout +25 on our starting line, and 4.3 percent of its voters split their ticket in recent elections.

Precinct 1151 (Bexar County) is a turnout race.

Stout's side leads Precinct 1151 (Bexar County) by about 22 points on our starting line, and it cast about 1,488 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 108 votes there.

Precinct 3075 (Bexar County) splits its ticket the most.

Of the precincts in this plan, Precinct 3075 (Bexar County) has the highest share of ticket splitters: 4.7 percent. That is where a persuasion call is most likely to reach someone open to crossing over.

The money is close.

As of June 30, 2026, Herrera had $309K in cash on hand to Stout's $171K. A race this close on money is decided on voter contact.

The evidence

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 Stout's side lost voters it won further up the ballot.

The next 37 days

Voting starts October 19.

  1. Now to October 5
    Find them

    Voter ID calls across the persuasion list in these precincts. Every conversation tags the voter: with Stout, with Herrera, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list.

  2. October 6 to 18
    Persuade

    Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 8,858 net votes from people who have crossed party lines before.

  3. October 19 to 25
    Bank the ballots

    Mail ballots are already going out, and in-person early voting runs October 19 through October 30. Mail ballot applications must be received by October 23. Chase every supporter's mail ballot request until it is returned, and move supporters to early voting while it is open.

  4. October 26 to November 2
    Turn them out

    The drop-off voters: people who voted in 2024 and skipped 2022. At least 35,129 of them live where Stout is favored. In-person early voting ends October 30. Mail ballots count if received by 7 p.m. on November 3, or by 5 p.m. on November 4 if postmarked by Election Day.

  5. November 3
    Election day

    Polls are open 7 a.m. to 7 p.m. Texas has no same-day registration; the registration deadline is October 5. The last calls go to identified supporters who have not voted, with their polling place in hand.

What has to be true

No wishful thinking.

Official results in this district: Trump carried the 2024 presidential race by 14.8 points; Cruz carried the 2024 U.S. Senate race by 8.2 points; Abbott carried the 2022 governor's race by 10.3 points.

  1. Stout wins 28 percent of the ticket splitters and undecided voters now leaning Herrera.
  2. In Precinct 1151 (Bexar County) and Precinct 1141 (Bexar County), 20 percent of the people who voted in 2024 but skipped 2022 come back and vote.
  3. No national wave is required. The plan closes at 57 percent of what recent Texas results show is possible.
  4. The starting line comes from published 2026 polls, including campaign or party sponsored polls where those are the only ones; if the true gap is different, so is the plan.
The work

3,783 conversations.

That is how many live voter conversations this plan takes: about 72,202 dials to 24,067 households, before the last ballot is cast.

live conversations: persuasion, voter ID, ballot chase

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.

HyperPhonebank

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 $8,346 at our published rates: 24,067 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.
