The U.S. midterm elections will be held on November 3, 2026. There are four candidates on the ballot for the U.S. Senate seat up for election in Alaska: Dan S. Sullivan (the incumbent), Daniel J. Sullivan, Jr., and Gerald Heikes, all of whom are running as Republicans, and Mary Peltola, running as a Democrat. Peltola, who formerly held Alaska’s seat in the U.S. House of Representatives, and the incumbent Senator Sullivan, who is seeking a third term, are considered to be the front-runners.
Under Alaska’s electoral system, a nonpartisan primary election was held on August 18. More than a dozen candidates were on the ballot, with the top four vote-getters—Peltola, Sullivan, Sullivan, and David Leslie (Democrat)—set to advance to the November 3 election. But Leslie withdrew from the race and was replaced by Heikes, who was the primary’s fifth-place candidate. Before the primary, Daniel J. Sullivan, Jr.’s candidacy was challenged over allegations that he was only running as a spoiler to draw votes away from the incumbent Sullivan, but a ruling by Alaska’s Supreme Court kept him on the ballot. He was not, however, listed on the ballot with his party affiliation. The winner of the Senate election on November 3 will be determined by ranked-choice voting.
