Plus a national shift of 0.1 points of margin (2,157 votes) that no campaign controls.

What has to be true
  1. Collins wins 50 percent of the ticket splitters and undecided voters now leaning Ossoff.
  2. In the precincts Collins's side carries in Cherokee County and Hall County, 35 percent of the people who voted in 2024 but skipped 2022 come back and vote.
  3. The national environment moves about 0.1 points toward Collins's side between now and November 3.
  4. 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.
