What has to be true
  1. Croisant wins 50 percent of the ticket splitters now leaning Tedford.
  2. In Precinct 720031 (Tulsa County) and Precinct 720090 (Tulsa County), 35 percent of the people who voted in 2024 but skipped 2022 come back and vote.
  3. The national environment moves about 14.8 points toward Croisant's side between now and November 3.
  4. 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.
