Incumbent Republican Sen. Susan Collins seeks re-election in the November 2026 Maine Senate race, facing presumptive Democratic nominee Graham Platner after Gov. Janet Mills suspended her primary bid on April 30 amid trailing polls. Recent Emerson (March) and other surveys show Platner leading Collins by 6-11 points in general election matchups, with polling averages around +7 for Democrats as of early May; Collins holds a 57% unfavorable rating. This consolidation of Democratic support and consistent polling edge, in a state Kamala Harris carried in 2024, underpin trader consensus pricing a 77.5% implied probability of a Democratic victory ahead of the June 9 primaries.
