Maine’s Senate race could help decide control of Congress

July 17, 2025

Senator Susan Collins, a longstanding Republican representing Maine since 1997, is expected to seek a sixth term in 2026 though she hasn't formally announced her candidacy. Despite Maine's Democratic leanings at the presidential level, Collins has historically been difficult to unseat, as demonstrated by her decisive victory over Democrat Sara Gideon in 2020 despite Gideon's substantial campaign funding. The 2026 race remains uncertain as potential candidates like term-limited Democratic Governor Janet Mills consider challenging Collins, while Democrats David Costello and Jordan Wood have already entered the primary.

Why it matters

This race is critical for Democrats' path to regain Senate control

Collins is the only Republican senator in a state that reliably votes Democratic at the presidential level
Collins has historically been difficult to defeat despite Maine's Democratic leanings
