ME Senate — Collins retention

Will Susan Collins (R) retain her Maine Senate seat in 2026?

EHIQ
62%
(58-68%)
Polymarket
Edge

Thesis

Collins won 2020 comfortably; moderate R popular in ME. BUT: EHIQ register read shows the highest desperation signal of any incumbent on the board — significantly elevated stress markers in her language vs other R incumbents. ME blue-leaning + Trump-era D enthusiasm could catalyze a strong D challenger. EHIQ tightens to 62% (vs typical LIKELY_WIN_R 70-75%) due to desperation signal.
