Maine Senate Polls: Collins Dominates, Dems in Disarray

February 23, 2026·1 day ago·via The New York Times

Incumbent GOP Senator Susan Collins crushes unknown Republican primary challengers and leads generic Democrats in recent polls, proving her staying power in deep-blue Maine. On the Democrat side, challenger Graham Platner surges past Governor Janet Mills for the nomination, thanks to strong support from socialists, progressives, and young voters. This battleground race, the only Republican Senate seat in a Kamala Harris-won state, stays firmly in Collins' column per UNH and other surveys.
