Updated October 26, 2026. This is a developing story; details may change.
Alaska’s U.S. Senate race has become one of the most closely watched contests of the 2026 midterms. ABC News rates it a tossup, and it has drawn attention for two unusual reasons: a second candidate who shares the incumbent’s name, and a federal legal fight over certifying the result.
How Alaska’s system works
Alaska uses a single all-party primary in which the top four finishers advance to the general election, where voters rank candidates in order of preference. In the August primary, Democrat Mary Peltola, a former congresswoman, received about 49.5% of the vote, Republican Sen. Dan Sullivan about 41.4%, and a second candidate, Dan J. Sullivan of Petersburg, about 2.5%, according to the Alaska Beacon. Because the two men share a name, the question of how the second Sullivan’s presence affects a close race has become a major talking point.
Competing claims
The incumbent’s allies have called the second Sullivan’s campaign a sham designed to confuse voters, though the Alaska Beacon noted they made the claim without providing evidence. Dan J. Sullivan has denied being a plant, and both he and the Alaska Democratic Party say the party was not involved in his candidacy. NBC News reported in August that the Justice Department had issued grand jury subpoenas related to his campaign; the Alaska Beacon said it could not verify that reporting at the time.
The certification lawsuit
More recently, Reuters reported that the Justice Department sued to block certification of a possible Democratic win in the Senate race, a step described as highly unusual. CNBC reported that Democrats and voting-rights groups are challenging that effort in court. We have not independently reviewed the court filings, and the case may move quickly.
Why it matters
Republicans hold a 53-47 Senate majority, and Alaska is one of the few seats where control could change. President Trump won the state by about 13 points in 2024, but Peltola has run as an independent-minded candidate and distanced herself from national Democrats.
