Why this race matters
Alaska uses ranked-choice voting in this statewide primary: all candidates run on one ballot; the top four advance to the general election. Incumbent Dan Sullivan (R) vs. former U.S. Representative Mary Peltola (D) vs. other major candidates. Peltola, the first Alaska Native in Congress, entered the race in January 2026. She is the only Democrat to win a statewide election in Alaska since 2008. Senator Lisa Murkowski (R), who previously endorsed Peltola for the House, has endorsed Sullivan in this race.
