Incumbent Republican Susan Collins faces Democratic nominee Graham Platner in the November 2026 general election for Maine’s Senate seat. Recent polls, including averages from Quantus Insights and others conducted in May and early June 2026, show Platner holding a narrow lead of roughly 3–6 points among likely voters. This positioning reflects Maine’s Democratic lean in federal contests, as the state supported Kamala Harris by about 7 points in 2024, alongside Collins’s status as the last Republican senator from New England. Platner secured the Democratic nomination with 72% of the vote in the June 9 primary after Governor Janet Mills suspended her bid in April. Race ratings classify the contest as a toss-up or slight Republican tilt, with trader consensus pricing the Democratic outcome higher due to these structural and polling dynamics.
