Overview
Maine Governor Janet Mills, 77, has officially launched her 2026 Senate campaign, aiming to challenge incumbent Republican Senator Susan Collins, 72, in a highly anticipated and pivotal election.
Democrats view Maine's Senate seat as a prime target to regain control of the Senate, as it is the only GOP-held seat in a state won by Kamala Harris in the last presidential election.
Mills' campaign emphasizes her past confrontations with President Trump and her opposition to his policies, positioning herself as an independent voice against the former president's agenda.
Before facing Senator Collins, Governor Mills must navigate a competitive Democratic primary against well-funded challengers like oyster farmer Graham Platner and former congressional aide Jordan Wood.
Senator Collins, who secured her fifth term in 2020, is expected to seek a historic sixth term, setting the stage for a high-stakes contest with significant national implications.
