What has to be true
  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.
