How
  • P
    Persuade
    472 voters who split their ticket in recent elections and lean Takano today.
    +472
  • M
    Mobilize
    There are almost no cities and unincorporated areas Manos's side carries, so turnout alone cannot help here.
    +0
  • C
    Consolidate
    Voters who went third party in recent races, in the cities and unincorporated areas that lean Manos's way.
    +270

Plus a national shift of 8.5 points of margin (11,628 votes) that no campaign controls.

What has to be true
  1. Manos wins 50 percent of the ticket splitters now leaning Takano.
  2. The national environment moves about 8.5 points toward Manos's side between now and November 3.
  3. No 2026 public poll exists for this race, so the starting line is a weighted blend of official recent results; the first real poll will move it.
