Democrats see a path to win the Senate. It's narrow and has little room for error

Senate Democratic leaders believe they have a path to winning the majority in November, though it’s one with very little wiggle room.

The party got a new burst of confidence when former Rep. Mary Peltola announced Monday she’ll run for the Senate in Alaska. Her bid gives Democrats a critical fourth candidate with statewide recognition in states where Republican senators are seeking reelection this year. Nationally, Democrats must net four seats to edge Republicans out of the majority.

That possibility looked all but impossible at the start of last year. And while the outlook has somewhat improved as 2026 begins, Democrats still almost certainly must sweep those four seats. First they must settle some contentious primaries, the mark of a party still struggling with its way forward after Republicans took full control of Washington in 2024. Importantly, they must also beat back challenges to incumbents in some of the most competitive states on the map.
