Mary Peltola And Sen. Dan Sullivan Advance In Alaska Top-Four Senate Primary
Incumbent Sen. Dan Sullivan and former Rep. Mary Peltola advanced from Alaska's all-party, top-four U.S. Senate primary held Tuesday, August 18, 2026, setting up a November contest that could help decide control of the Senate.[1]
Peltola outraised Sullivan in the primary cycle, collecting about $18 million and ending July with roughly $4.6 million cash on hand, compared with Sullivan's $11.7 million raised and about $7.3 million on hand.[2] The result came from a 16-candidate field and occurred even as retired Petersburg teacher Daniel J. Sullivan won a legal fight to remain on the ballot and is widely viewed as a potential spoiler for the incumbent.[2]
Sen. Sullivan is running for a third term and has the endorsement of President Donald Trump.[2] Senate Minority Leader Chuck Schumer recruited Peltola, and national Democrats see the Alaska seat as one of their best opportunities to retake the Senate.[2] Alaska law will send the November contest to ranked-choice voting, making lower-preference transfers likely decisive if no candidate wins a majority.[1]
National Republicans described Sullivan's primary advancement as a boost to GOP optimism, even as some party figures condemned the same-name challenger as a deliberate spoiler attempt.[2]
