Peltola leads Sullivan in March poll for Alaska Senate seat

Democrat Mary Peltola leads Republican Senator Dan Sullivan in the race for Alaska's U.S. Senate seat, a March 2026 Alaska Survey Research poll shows.

Peltola held a five-point advantage over Sullivan among likely general-election voters in the poll, which surveyed 1,590 Alaskan adults from March 19 to 22, including 1,512 registered voters. The poll reported a margin of error of approximately 2.5 to 3.0 percentage points at the 95 percent confidence level. Both candidates registered high name recognition statewide, with Peltola's positive favorability rating at 48.5 percent in March 2026, compared with 40.7 percent positive for Sullivan, while Sullivan's negative rating remained above 50 percent.

In 2022, Mary Peltola won Alaska's at-large U.S. House seat in a special election and then the regular general election, becoming the first Alaska Native member of Congress. Dan Sullivan has represented Alaska in the U.S. Senate since 2015 and is seeking a third term in the November 2026 election.

Under Alaska's ranked-choice voting system, a candidate who receives more than 50 percent of first-choice votes wins without additional counting rounds. The 2026 primary is scheduled for August 18, with the general election on November 3.
