Alaska is among the states Democrats must carry if they are to flip the four seats needed to reclaim the Senate majority, making Peltola’s entry one of the more consequential candidacy announcements of the 2026 midterm cycle.
Former U.S. Rep. Mary Peltola, the first Alaska Native to serve in Congress, announced Monday she will challenge Republican Sen. Dan Sullivan in the 2026 midterm election, drawing immediate praise from national Democrats who have been working to recruit high-profile candidates in states where their path to a Senate majority runs through deep-red terrain.
Peltola, who is Yup’ik, made the announcement in a video that centered on the economic pressures bearing down on Alaskans, particularly those in rural communities far from the state’s limited road system. She said the salmon and migratory birds that once sustained Alaska Native subsistence hunters are now harder to find, pushing families toward grocery stores where high transportation costs drive prices to extremes.
“It’s not just that politicians in D.C. don’t care that we’re paying $17 for a gallon of milk in rural Alaska,” Peltola said. “They don’t even believe us. They’re more focused on their stock portfolios than our bank accounts.”
A contested path in Republican-leaning territory
Democrats must flip four seats to win the majority in the 100-member Senate — a task that requires dislodging incumbents in states Donald Trump carried in the most recent presidential election while simultaneously defending their own incumbents elsewhere. Alaska, which Trump won, is among the states on that map.
Sullivan has held the seat since 2015, when he defeated the state’s last Democratic senator. A former state attorney general and natural resources commissioner, he reported $4.7 million available in his campaign finance report covering the third quarter of 2025. Sullivan was endorsed by Trump in 2020.
Sullivan’s campaign spokesman Nate Adams said the senator “has spent years delivering real results” while “his opponent served a term and a half in Congress where she didn’t pass a single bill.”
The Republican National Committee, in a statement from spokesman Nick Poche, said Peltola “became a rubber stamp for the far-left the second she got to Washington” and predicted she would lose.
Peltola’s record and cross-party appeal
Peltola won Alaska’s sole House seat in both a special election and a regular election in 2022, defeating a field that included Republican former Gov. Sarah Palin. She lost the seat in 2024 to Republican Nick Begich, who had run unsuccessfully in 2022.
During her time in Congress, Peltola cultivated a cross-partisan profile that drew attention beyond Alaska’s borders. She supported the Willow oil development project on the North Slope, a position that put her at odds with many national Democrats. She also declined to endorse then-Vice President Kamala Harris in the 2024 presidential race.
She invoked Republican former Sen. Ted Stevens in her announcement, saying Alaska’s congressional delegation once set partisanship aside to back public media and disaster relief — and arguing that spirit has been lost.
“It’s about time Alaskans teach the rest of the country what Alaska First and, really, America First looks like,” Peltola said.
Party reaction and electoral structure
National Democrats responded with enthusiasm. Eric Croft, chair of the Alaska Democratic Party, called Peltola “our most steadfast champion and a strong voice for Alaskans in every region of our state.” Lauren French, a spokesperson for the Senate Majority PAC, said Peltola’s entry “completely upends the campaign.”
Alaska’s electoral structure may work in Peltola’s favor. Most registered voters in the state are unaffiliated with either major party, and both chambers of the state legislature are controlled by bipartisan coalitions. The state uses open primaries and ranked choice voting in general elections; the top four vote-getters in the August primary, regardless of party affiliation, advance to the November general election.
Peltola’s candidacy will be tested in part by her ability to reactivate the coalition that elected her in 2022 while broadening her appeal among the unaffiliated voters who have made Alaska a competitive state for candidates willing to work across party lines.
