The plan on this page sits at 40%. Median outcome at this setting: Conroy by 724.

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
11K
net votes in the plan, from a pool of 27,372

Who. Ticket splitters and the 10 percent still undecided in the latest poll: 27,372 leaning Landsman today.

How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. Conroy needs to win 20 percent of the ones now leaning Landsman.

Mobilize
2,484
net votes in the plan, from a pool of 50,025

Who. At least 50,025 people who voted in 2024 but not in 2022, in precincts where Conroy'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
233
net votes in the plan, from a pool of 1,652

Who. Voters who went third party in recent races, in the precincts that lean Conroy'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: 13,741 net votes against a gap of 13,087. That is a win.

What the numbers say that the polls do not

The hidden path.

Deerfield Twp Cc (Warren County) carries the most.

Deerfield Twp Cc (Warren County) gives this plan more net votes than any other precinct: 119. It sits at Conroy +9 on our starting line, and 13.8 percent of its voters split their ticket in recent elections.

Mason City G (Warren County) splits its ticket the most.

Of the precincts in this plan, Mason City G (Warren County) has the highest share of ticket splitters: 14.7 percent. That is where a persuasion call is most likely to reach someone open to crossing over.

Spend it where it counts.

As of June 30, 2026, Landsman had $3.61 million in cash on hand to Conroy's $474K. That is exactly why the plan puts every dollar on the few places listed here instead of the whole map.

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

The next 37 days

Voting starts October 6.

  1. Now to October 5
    Find them

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

  2. October 6 to 16
    Persuade

    Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 11,024 net votes from people who have crossed party lines before.

  3. October 17 to 25
    Bank the ballots

    In-person early voting runs October 6 through November 1 at each county board of elections, and absentee ballots start going out October 6. Absentee ballots must be received by 7:30 p.m. on November 3; a 2025 law ended the postmark grace period. 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 50,025 of them live where Conroy is favored. Absentee ballots must be received by the county board of elections by 7:30 p.m. on November 3; a postmark no longer counts. Applications must be received by October 27.

  5. November 3
    Election day

    Polls are open 6:30 a.m. to 7:30 p.m. and photo ID is required. Ohio 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 2.6 points; Brown carried the 2024 U.S. Senate race by 2.3 points; Vance carried the 2022 U.S. Senate race by 0.1 points.

  1. Conroy wins 20 percent of the ticket splitters and undecided voters now leaning Landsman.
  2. No national wave is required. The plan closes at 40 percent of what recent Ohio results show is possible.
  3. 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

3,958 conversations.

That is how many live voter conversations this plan takes: about 75,531 dials to 25,177 households, before the last ballot is cast.

25K
households on the target list
76K

3,958
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 $8,419 at our published rates: 25,177 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.
