How Sam Forstag wins.

A true toss-up between Forstag and Flint: the 2 public 2026 polls average within one point. In a tied race, the plan aims for a 2-point cushion: 5,008 net votes, most of them in Silver Bow County, Missoula County and Lake County.

Starting line: a tie (the 2 public 2026 polls average within one point), applied to each county's pattern in the 2022 and 2024 official returns. In a tied race the plan aims for a 2-point cushion. 2026 turnout modeled on 2022, the last midterm.

The odds

50% today. 66% with the plan.

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.

The plan on this page sits at 19%. Median outcome at this setting: Forstag by 5,308.

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
4,401
net votes in the plan, from a pool of 22,688

Who. Ticket splitters and the 12 percent still undecided in the latest poll: 22,688 leaning Flint today.

How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. Forstag needs to win 10 percent of the ones now leaning Flint.

Mobilize
590
net votes in the plan, from a pool of 41,855

Who. At least 41,855 people who voted in 2024 but not in 2022, in counties where Forstag'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
267
net votes in the plan, from a pool of 3,939

Who. Voters who went third party in recent races, in the counties that lean Forstag'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: 5,258 net votes against a gap of 5,008. That is a win.

What the numbers say that the polls do not

The hidden path.

The ratings are moving.

On September 25, the Cook Political Report moved Montana's 1st from Likely Republican to Lean Republican. The three public polls since June range from Flint by one to Forstag by two.

Silver Bow County carries the most.

Silver Bow County gives this plan more net votes than any other county: 1,828. It sits at Forstag +23 on our starting line, and 11.8 percent of its voters split their ticket in recent elections.

Missoula County is a turnout race.

Forstag's side leads Missoula County by about 33 points on our starting line, and it cast 16,866 more ballots in 2024 than in 2022. Roughly that many of its 2024 voters sat out the last midterm; bringing enough of them back nets 590 votes there.

Forstag has the cash edge.

As of June 30, 2026, the close of the latest FEC reporting period, Forstag had $550K in cash on hand to Flint's $502K. The underdog can fund the contact this plan takes.

The next 37 days

Voting starts October 9.

  1. Now to October 8
    Find them

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

  2. October 9 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 4,401 net votes from people who have crossed party lines before.

  3. October 19 to 27
    Bank the ballots

    Montana mails absentee ballots starting October 9, and in-person absentee voting runs at county election offices until noon on November 2. Mail ballots must be received by 8 p.m. on November 3; a postmark does not count. Chase every supporter's mail ballot request until it is returned, and move supporters to early voting while it is open.

  4. October 28 to November 2
    Turn them out

    The drop-off voters: people who voted in 2024 and skipped 2022. At least 41,855 of them live where Forstag is favored. Mail ballots must be received by 8 p.m. on November 3; a postmark does not count.

  5. November 3
    Election day

    Polls are open 7 a.m. to 8 p.m. Montana registers voters at the county election office through 8 p.m. on Election Day. 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: the Republican nominee carried the 2024 House race by 7.7 points; Trump carried the 2024 presidential race by 11.6 points; Tester carried the 2024 U.S. Senate race by 0.7 points.

  1. Forstag wins 10 percent of the ticket splitters and undecided voters now leaning Flint.
  2. In Missoula County, 7 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 19 percent of what recent Montana 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

1,641 conversations.

That is how many live voter conversations this plan takes: about 31,309 dials to 10,436 households, before the last ballot is cast.

10K
households on the target list
31K

1,641
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 $4,657 at our published rates: 10,436 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.
