    +20,309
  • M
    Mobilize

  • C
    Consolidate
    Voters who went third party in recent races, in the counties that lean Miller's way.
    +2,049

Plus a national shift of 14.7 points of margin (32,124 votes) that no campaign controls.

What has to be true
  1. Miller wins 50 percent of the ticket splitters and undecided voters now leaning Downing.
  2. The national environment moves about 14.7 points toward Miller's side between now and November 3.
  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.
