Judge Rules Challenger Can Compete in Alaska Senate Primary

On June 27, 2026, Superior Court Judge Thomas Matthews ruled in favor of allowing a challenger with the same name and party affiliation as Alaska Republican U.S. Senator Dan Sullivan to participate in the upcoming primary election. This decision overturns a previous ruling by Division of Elections Director Carol Beecher that disqualified the candidate, Dan J. Sullivan, from appearing on the primary ballot.

The state has set a deadline for a final ruling by Tuesday to facilitate the printing of ballots for the August 18 primary election. Judge Matthews found the division’s decision to exclude Dan J. Sullivan lacked constitutional or legal basis, instead being based on a new ‘good faith’ criterion.

Sam Curtis, spokesperson for the state Department of Law, confirmed the division’s intention to appeal this ruling to the Alaska Supreme Court. Jeffrey Robinson, the legal representative for Dan J. Sullivan, withheld further comment pending the Supreme Court’s decision.

The dispute highlights the importance of the incumbent’s reelection campaign, with the Alaska race considered competitive among U.S. Senate contests this fall. Democrats aim to flip this seat in their bid to regain the majority, despite challenges in a state historically leaning Republican.

The sitting senator and his supporters have criticized the challenger’s campaign as potentially misleading to voters. An investigation into Dan J. Sullivan’s candidacy was initiated by Republican Lt. Gov. Nancy Dahlstrom earlier this month. Under Alaska’s system, the top four candidates, regardless of party, advance from the primary to the ranked-choice general election in November.

Senator Sullivan accuses the challenger of collaborating with Democrats, including the campaign of Democratic contender Mary Peltola, to create electoral confusion. The senator publicly alleged Democrats are attempting to deceive Alaskans and skew the election outcome. However, Peltola’s campaign and state Democrats, along with the challenger, deny these claims.

Beecher argued the challenger’s candidacy was not submitted in good faith, pointing to similarities in campaign materials and consulting ties. No evidence of coordination was cited. Beecher noted that the challenger had altered his party registration and voter details, further raising doubts about his candidacy’s legitimacy.

In defense, Dan J. Sullivan’s attorneys assert that U.S. Senate qualifications are strictly defined by the Constitution, covering age, citizenship, and residency, without additional criteria. They contend Beecher had no authority to exclude their client from the ballot.

Retired educator and former U.S. Forest Service employee, Dan J. Sullivan, argues his shared name and affiliation provide visibility in the race. Nevertheless, he expressed persistent dissatisfaction with the incumbent senator’s performance.

Both Dan J. Sullivan and the senator have filed as candidates, with prior certification distinguishing them by middle initials.
