Two candidates named Dan Sullivan are running for Alaska's U.S. Senate seat and will be distinguished on the ballot by their middle initials, as required by state law to reduce voter confusion. Incumbent Senator Dan Sullivan (R-AK) is seeking re-election against former Democratic Representative Mary Peltola, who is campaigning to help the party regain a Senate majority in 2026. Another Republican candidate, Dan J. Sullivan, has entered the race, leading to the ballot distinction where the incumbent will be listed as "Dan S. Sullivan" and the challenger as "Dan J. Sullivan."
Dan J. Sullivan announced his candidacy last week, criticizing the incumbent for not prioritizing Alaska's interests. He stated, "For too long, Senator Sullivan has failed to put Alaska first." The race has generated controversy, with accusations from Republicans that Democrats are supporting Dan J. Sullivan to siphon votes from the incumbent. Alaska's open primary system allows all candidates to compete on the same ballot, meaning both Sullivans will appear together in the August primary.
Senator Sullivan alleged that Democrats are attempting to manipulate the race to confuse voters, a claim that Peltola's campaign has denied. The National Republican Senatorial Committee has also intervened, urging Alaska election officials to remove Dan J. Sullivan from the ballot, citing regulations against misleading candidates. This situation is not unprecedented in Alaska, as a similar name confusion occurred when Senator Sullivan was first elected in 2014. The primary election is scheduled for August 18, 2026.
