Former Rep. Mary Peltola is challenging GOP Sen. Dan Sullivan in Alaska, potentially putting a tough race in reach for Democrats. 

Peltola, a Democrat who served one term as Alaska’s at-large U.S. House representative from 2022 to 2025, was widely seen as a prized top recruit for the race and for national Democrats, who have an uphill battle to reclaim control of the U.S. Senate in 2026. 

Peltola, the first Alaska Native person elected to Congress, focused on supporting Alaska’s fisheries while in office. 

“My agenda for Alaska will always be fish, family and freedom,” Peltola said in her announcement video Monday. “But our future also depends on fixing the rigged system in D.C. that’s shutting down Alaska while politicians feather their own nest.” 

“It’s about time Alaskans teach the rest of the country what Alaska first and really, America first, looks like,” she added.  

A 2025 survey by progressive pollster Data for Progress, which regularly polls Alaska voters, found that Peltola has the highest approval rating of any elected official in the state. She narrowly lost reelection to Republican Rep. Nick Begich in 2024. 

Elections in Alaska are conducted with top-four nonpartisan primaries and ranked-choice general elections. In the Data for Progress poll, 46 percent of voters said they would rank Sullivan first and 45 percent said they would rank Peltola first in a matchup for U.S. Senate. Sullivan won reelection by a margin of 13 points in 2020. 

Republicans control the Senate by a three-seat majority, 53 to 47, and senators serve six-year terms, meaning a third of the Senate is up every election cycle. For Democrats to win back the chamber in 2026, they’d need to hold competitive seats in states like Georgia and Michigan while flipping four GOP-held seats in Maine, North Carolina and even more Republican-leaning states like Alaska, Ohio, Iowa, Nebraska and Texas.
