The Dan Sullivan Senate race in Alaska won’t feature two candidates with the same name after all. On Monday, state officials ruled that only one Dan Sullivan will appear on this year’s ballot, ending a strange episode that had Republicans crying foul over what they called a deliberate scheme to mislead voters.

One Name, Two Candidates

At the center of the controversy was Dan J. Sullivan, a political newcomer whom Republicans accused of being a Democratic plant. Their argument was straightforward: by sharing a name with the sitting senator, Dan S. Sullivan, the newcomer could siphon away votes and muddy the waters in an already competitive contest.

The state’s Division of Elections sided against the challenger and removed him from the ballot.

Why a Shared Name Matters So Much

Alaska’s election system makes the stakes of a duplicate name unusually high. The state runs an open primary in which candidates from every party appear together on a single ballot. The top four finishers then advance to a general election decided by ranked-choice voting.

In that setup, two candidates carrying the name “Dan Sullivan” could easily split the incumbent’s support, potentially reshaping the outcome of a race that both parties are watching closely.

The senator, Dan S. Sullivan, is defending his seat against former Representative Mary Peltola, a Democrat who served Alaska from 2022 to 2025. Democrats see the state as a genuine opportunity to flip a Republican seat, which raised the temperature around any move that might disadvantage the incumbent.

The Complaints Pile Up

Dan J. Sullivan’s candidacy drew objections at both the state and federal levels, with critics alleging he was acting in bad faith. One detail that fueled suspicion was that a communications consultant working for his campaign had previously voiced open support for Peltola.

Peltola’s campaign, for its part, has consistently denied any connection to the Dan J. Sullivan effort.

The matter escalated last week when Lieutenant Governor Nancy Dahlstrom, a Republican, launched an investigation into the challenger’s candidacy.

The Ruling and Its Reasoning

After reviewing the case, Dahlstrom agreed with the Republican objections and informed Dan J. Sullivan on Monday that he would be left off the ballot. Her decision leaned on several specific findings:

• He asked to be listed simply as “Dan Sullivan,” despite being registered to vote under the clearer name “Daniel J. Sullivan Jr.”
• At one stage, he even requested to appear on the ballot using the senator’s own name and middle initial.
• His campaign website and logo appeared to closely imitate those of the incumbent.
• He had never been affiliated with the Republican Party in Alaska before launching this campaign.

These were largely the same points Republicans had pressed in their effort to disqualify him.

Reactions From Both Sides

The senator’s campaign welcomed the ruling in strong terms. Billy Mackey, campaign manager for Dan S. Sullivan, framed it as a matter of protecting the integrity of the vote, thanking Dahlstrom for shielding Alaskans from what he described as a sham candidate designed to confuse voters and tilt the race toward Peltola.

Dan J. Sullivan did not immediately respond to a request for comment, but he has defended himself before. He maintains that he met every legal requirement to run and filed under his own legal name. He has also explained his recent Republican affiliation by pointing to his earlier ties to the Alaskan Independence Party.

In a statement issued before the decision came down, he cast himself as a qualified candidate caught in a politically driven process. He argued that unsupported accusations were being treated as credible while operatives worked to keep him off the ballot, and he suggested Alaskans had reason to question whether politics, rather than fair application of the law, was guiding the outcome.

What Happens Next

The challenger’s candidacy is already marked as “denied” on the Division of Elections website. He has 30 days to file an appeal, though time is tight: Dahlstrom noted that ballots are scheduled to be printed on June 28, leaving a narrow window for any reversal to take effect.

For now, the ruling clears the way for a head-to-head contest between Senator Dan S. Sullivan and Mary Peltola, free of the naming confusion that briefly threatened to upend it. This remains a developing political story, and an appeal could keep the dispute alive in the days ahead.
