The 2026 Maine Senate race features Republican incumbent Susan Collins seeking a sixth term against likely Democratic nominee Graham Platner, an oyster farmer and veteran who emerged after Governor Janet Mills withdrew from the Democratic primary in late April. Recent head-to-head polling shows Platner holding a narrow edge, reflecting Maine's mix of moderate Republican strength and broader Democratic advantages in presidential voting. With primaries set for June 9 and the general election on November 3, traders view the contest as competitive yet favor Democrats based on the state's partisan leanings and Collins' primary challenges from the right.
