Recent polling averages show Democratic challenger Graham Platner leading incumbent Republican Sen. Susan Collins by 5-7 points in the 2026 Maine Senate race, fueling trader consensus at 77.5% for a Democratic win. Platner, a Marine veteran and oyster farmer, solidified as the presumptive nominee after Gov. Janet Mills exited in April, with his internal and public surveys like Echelon Insights (Platner 50-51%, Collins 45%) dominating headlines. Collins, seeking a sixth term at age 73, faces headwinds from dueling campaign ads launched last week marking the general election kickoff, amid Maine's ranked-choice voting system and a competitive primary on June 9. A NRCC poll in Trump-won ME-02 showed Collins up 11 points, but statewide trends hold the edge for Democrats.
