Democrat Mary Peltola advanced to Alaska’s U.S. Senate general election after winning the primary on August 18, 2026, with 48% of the vote, setting up a competitive matchup against incumbent Republican Senator Dan Sullivan, who finished second with 42.8%.
The general election on November 3, 2026, will pit two of Alaska’s most prominent political figures against each other in what analysts have called one of the most competitive Senate races in the country. Peltola, a Yup’ik woman from Alaska, emerged as the top Democratic candidate in a crowded field of 16 candidates competing under Alaska’s top-four primary system.
Peltola is a former U.S. Representative who made history in 2022 when she won a special election to fill the seat left vacant by the death of Representative Don Young, becoming the first Alaska Native elected to Congress. She was re-elected to a full term that same year but lost her House seat in 2024 to Republican Nick Begich III in a ranked-choice voting contest.
Sullivan, a Republican who has served in the Senate since 2015, is seeking his third term. He easily advanced from the primary despite facing a strong challenge from Peltola, whose campaign has gained momentum since her January 2026 announcement of entry into the race. Peltola’s candidacy transformed Alaska into a competitive battleground for national Democrats, according to reporting from the Democratic Senatorial Campaign Committee.
Recent polling shows the race remains tight. One poll conducted in March 2026 showed Peltola ahead of Sullivan 49% to 44%, while other surveys have shown the race within a few percentage points either way. An August poll showed Peltola leading 52% to 48% after undecided voters were accounted for, though another recent survey placed Sullivan ahead 47% to 45%.
If elected, Peltola would become the first Native American or Alaska Native woman to serve in the U.S. Senate, according to the Center for American Women and Politics at Rutgers University. Democrats have not won a Senate election in Alaska since 1992, making the state a crucial target for the party’s 2026 strategy.
