How
  • P
    Persuade
    3,014 voters who split their ticket in recent elections and lean Liccardo today.
    +3,014
  • M
    Mobilize
    There are almost no cities and unincorporated areas Soulé'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 Soulé's way.
    +357

Plus a national shift of 44.4 points of margin (117,664 votes) that no campaign controls.

What has to be true
  1. Soulé wins 50 percent of the ticket splitters now leaning Liccardo.
  2. The national environment moves about 44.4 points toward Soulé'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.
