How Sean McCann wins.
A true toss-up between McCann and Huizenga: the 3 head-to-head 2026 polls between the two finalists average within one point. In a tied race, the plan aims for a 2-point cushion: 6,921 net votes, most of them in Portage, Kalamazoo and Texas Township (Kalamazoo County).
McCann can win. The plan uses 26 percent of what history allows.
173,015 votes.
That is half of the 346,029 ballots we expect in this race, plus one. Where McCann stands today, and what is missing:
Starting line: a tie (the 3 head-to-head 2026 polls between the two finalists average within one point), applied to each community'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.
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.
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.
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. 23,084 voters in play: ticket splitters now leaning Huizenga, plus the 7 percent still undecided in the latest poll.
How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. McCann needs to win 13 percent of the ones now leaning Huizenga.
Who. At least 33,797 people who voted in 2024 but not in 2022, in cities and townships where McCann'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 cities and townships that lean McCann'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: 7,266 net votes against a gap of 6,921. That is a win.
12 cities and townships carry 80% of it.

The hidden path.
Portage carries the most.
Portage gives this plan more net votes than any other community: 1,822. It sits at McCann +23 on our starting line, and 7.7 percent of its voters split their ticket in recent elections.
Kalamazoo is a turnout target.
McCann's side leads Kalamazoo by about 64 points on our starting line, and it cast about 7,843 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 570 votes there.
Otsego Township (Allegan County) splits its ticket the most.
Of the cities and townships in this plan, Otsego Township (Allegan County) has the highest share of ticket splitters: 8.6 percent. That is where a persuasion call is most likely to reach someone open to crossing over.
The money is close.
As of July 15, 2026, Huizenga had $2.27 million in cash on hand to McCann's $1.69 million. A race this close on money is decided on voter contact.

Ballots are already coming in.
- Now to October 9Find them
Voter ID calls across the persuasion list in these cities and townships. Every conversation tags the voter: with McCann, with Huizenga, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list, starting now: ballots are already being cast.
- October 10 to 23Persuade
Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 5,899 net votes from people who have crossed party lines before. Every supporter it finds goes straight onto the ballot chase.
- October 24 to 30Bank the ballots
Absentee ballots have been available since September 24, with no excuse needed, and every community offers early in-person voting at least October 24 through November 1. Absentee ballots must reach the clerk by 8 p.m. on November 3. Chase every supporter's mail ballot until it is returned, and move supporters to early voting while it is open.
- October 31 to November 2Turn them out
The drop-off voters: people who voted in 2024 and skipped 2022. At least 33,797 of them live where McCann is favored. Absentee ballots must reach the city or township clerk by 8 p.m. on November 3; a postmark does not count. Voters can register in person at their clerk's office and vote the same day.
- November 3Election day
Polls are open 7 a.m. to 8 p.m. Voters are asked for photo ID but can sign an affidavit instead, and same-day registration is available at the clerk's office. 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 5.5 points; Rogers carried the 2024 U.S. Senate race by 6.1 points; Whitmer carried the 2022 governor's race by 0.8 points.
- McCann wins 13 percent of the ticket splitters and undecided voters now leaning Huizenga.
- In Kalamazoo and Benton Harbor, 9 percent of the people who voted in 2024 but skipped 2022 come back and vote.
- No national wave is required. The plan uses 26 percent of what recent Michigan results show is possible.
- The starting line comes from the published 2026 head-to-head polls between these two finalists, sponsored ones included; if the true gap is different, so is the plan.
1,827 conversations.
That is how many live voter conversations this plan takes: about 34,859 dials to 11,620 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 $5,185 at our published rates: 11,620 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.
