How
  • P

    +9,108
  • M

    At least 2,575 people who voted in 2024 but not in 2022, in precincts where Kahl's side wins at least 55 percent.
    +197
  • C
    Consolidate
    Voters who went third party in recent races, in the precincts that lean Kahl's way.
    +1,693

Plus a national shift of 32.4 points of margin (105,462 votes) that no campaign controls.

What has to be true
  1. Kahl wins 50 percent of the ticket splitters now leaning Bonamici.
  2. It would take a national shift of about 32.4 points toward Kahl's side, larger than any midterm swing in recent memory.
  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.
