Trump administration files lawsuit to block possible Democratic win in Alaska Senate race

The Trump administration has filed a lawsuit to block certification of the Senate race in Alaska if Republican Sen. Dan Sullivan loses the contest while another candidate with the same name is on the ballot, kicking off what many have feared could become a lengthy battle between the U.S. government and states over certifying an election where the president’s party is struggling.

Many in both parties believe the fight could come down to Alaska, where Sullivan faces Democrat Mary Peltola. Also on the Alaska ballot is a Daniel J. Sullivan from the tiny fishing community of Petersburg. He has said he decided to run on his own, but Republicans have contended he’s a Democratic plant to siphon votes away from their candidate.

On Thursday, the Department of Justice filed a lawsuit in federal court in Alaska demanding that the state be blocked from certifying a Peltola win if the other Sullivan remains on the ballot. “The United States accordingly brings this lawsuit to protect the integrity of the 2026 Senate election in Alaska,” the lawsuit alleges, contending that federal law requires states to protect the integrity of federal elections.

The Alaska Supreme Court rejected previous Republican efforts to remove the other Sullivan from the ballot, and the state’s Republican officials made the decisions about how to list him on the ballot. The other Sullivan will appear without a party designation next to his name, while the senator will be listed as the Republican incumbent. Alaska’s ranked choice voting system also will allow voters to select both of the men if confused.
