Republican Senator Susan Collins will compete against Democrat Graham Platner in the upcoming Senate election, as projected by NBC News. Both candidates secured their party nominations in the primaries held on June 6, 2026. Collins, who has served in the Senate since 1996, ran unopposed for her renomination, while Platner, a newcomer and veteran, faced minimal competition after former Governor Janet Mills suspended her campaign.
The election is expected to be significant for the Democratic Party, as they aim to gain control of the Senate. Currently, Democrats hold 47 seats and need a net gain of four to achieve a majority. Collins, the only Republican senator from a state that President Donald Trump lost in 2024, is considered a target for Democrats. Despite previous attempts to unseat her, Collins has successfully won re-election, including a notable victory in 2020.
Platner's campaign is characterized by his outsider status and progressive platform, which includes proposals to reform the political system and expand social programs. However, he faces scrutiny over past controversies, including allegations of troubling behavior and social media posts that have raised concerns among some Democratic leaders. Despite these challenges, prominent figures such as Senators Bernie Sanders and Elizabeth Warren continue to support him. Polls indicate a competitive race between Collins and Platner as the election approaches.
