Maine Gov. Janet Mills on Tuesday launched her much-anticipated challenge to Republican Sen. Susan Collins, landing Democratic leadership a prized recruit and likely setting up a generational test for the party in its quest to win back power in Washington.
Mills joins a Democratic primary that already includes oyster farmer Graham Platner, who’s reported strong fundraising and picked up considerable progressive support. The Maine race is seen as Senate Democrats’ best pickup opportunity in 2026 as the only GOP-held seat in a state won by Kamala Harris last year.
“My life’s work has prepared me for this fight – and I’m ready to win,” Mills said in her announcement video.
