Dan Sullivan

Senate Majority Leader John Thune criticized Alaska's election system this week, calling a challenge facing Republican Sen. Dan Sullivan's reelection campaign "bizarre" and suggesting it was designed to confuse voters.

Discussing Alaska's 2026 Senate race, Thune pointed to the presence of another candidate named Dan Sullivan among the challengers seeking the seat held by the Republican incumbent.

"This thing in Alaska is bizarre," Thune said. "I mean, really, and whoever contrived that — hopefully you guys will figure that out over time, but that obviously is designed to confuse the electorate in the state of Alaska."

"I think that any disruption in the political ecosystem right now is probably designed by Democrats to give their candidates an advantage," he added.

The comments come as Alaska’s U.S. Senate race draws increasing attention ahead of next year’s election. Sullivan, who was first elected to the Senate in 2014 and won reelection in 2020, is seeking a third term.

According to state election records, the race includes 16 candidates, among them another candidate named Dan Sullivan. The shared name has sparked questions among Republicans about whether voters could mistakenly support the wrong candidate on the ballot.

Thune did not provide evidence that the candidacy was organized to affect the election outcome, but suggested the situation warranted scrutiny.

The South Dakota Republican’s remarks underscore concerns some GOP officials have raised about Alaska’s election system, which differs from those used in most other states.

Alaska voters approved a ballot initiative in 2020 establishing a nonpartisan primary in which all candidates compete on a single ballot, with the top four finishers advancing to the general election. The state also uses ranked-choice voting in general elections.

Sullivan told reporters in Washington on Tuesday that he believes the appearance on the state's primary ballot of another Republican with the same name is a dirty political trick coordinated by Democrats and the campaign of his chief rival, former Democratic U.S. Rep. Mary Peltola. He threatened a lawsuit to get to the bottom of it.

"Everybody in Alaska knows I'm Dan Sullivan-R. So he's trying to do that. Why?" the senator said of the other Dan Sullivan. "He's not an R. He's purposely trying to trick my constituents to rig the election for Peltola."

A spokesman for the Peltola campaign, Harry Child, said it "has no involvement with either Sullivan campaign." Jenny-Marie Stryker, executive director of the Alaska Democratic Party, said her organization "is in no way affiliated with either Dan Sullivan."

The race remains in its early stages, and the final list of candidates could change before ballots are printed. Still, the unusual circumstance of two candidates with the same name has already become a point of discussion among Republican leaders.

Thune said the situation appears intended to create uncertainty among voters, describing it as an effort that "obviously is designed to confuse the electorate in the state of Alaska."

A spokesperson for Thune did not immediately respond to an email seeking additional comment.
