Alaska Senate Race 2026: Mary Peltola vs. Dan Sullivan
By Drooid · · How we work
Core Contest
The 2026 U.S. Senate race in Alaska pits Democratic former congresswoman Mary Peltola against incumbent Republican Sen. Dan Sullivan. Peltola, the first Alaska Native elected to Congress, won a 2022 special election for the state’s at-large House seat and lost the 2024 race for that seat to Nick Begich. Sullivan, a former state attorney general and natural-resources commissioner, was first elected to the Senate in 2014 and is seeking a third term. The ballot also includes a second Republican, Dan J. Sullivan Jr., and Gerald L. Heikes, a perennial candidate.
Background & Context
Alaska has long voted Republican in presidential contests but has elected Democrats to statewide offices, including Peltola’s 2022 House win. The state adopted ranked-choice voting in 2020, first using it in the 2022 election cycle. Voters rank candidates; if no one obtains an absolute majority, the lowest-ranked candidate is eliminated and their votes are redistributed until a majority is reached. This can extend the tabulation period after Election Day.

Issues and Campaign Themes
Data-center development – Sullivan promotes Alaska as a hub for AI-related data centers, citing cold weather, abundant gas, land, and water. Critics argue the projects generate limited jobs and create noise and water-pollution problems for nearby residents.
Energy and fuel costs – Sullivan argues expanded oil and gas production could lower fuel prices, while Peltola links high fuel costs to the war in Iran and advocates continued support for Ukraine.
Foreign-fuel imports – Both oppose importing Russian diesel; Sullivan called the idea “not a good idea,” and Peltola called buying fuel from Russia “terrible” and “foolish.”
Official Statements & Responses
- Senator Sullivan urged tech executives to locate data centers in Alaska, emphasizing the state’s natural advantages.
- Local resident Sarah Hollister expressed concern that data-center projects could degrade land for future generations.
Criticism & Opposition
- Sen. Mike Lee (Utah) condemned Slotkin’s remarks, calling them “absolutely disgraceful.”
- Community members near proposed data-center sites warned that “vacuum-cleaner-level” noise and environmental impacts threaten quality of life.
Conflicting Reports & Gaps
Poll results vary modestly, with leads ranging from a 2-point advantage for Peltola (Rasmussen) to a 5-point advantage (InsiderAdvantage). The Quantus Insights poll shows a statistical tie, highlighting the race’s volatility and the lack of a definitive consensus on voter preference.
What’s Next
Ballots are cast on November 3. Because Alaska uses ranked-choice voting, first-choice totals will be reported immediately, but full tabulation—including any necessary elimination rounds—may take up to two weeks, potentially delaying the final declaration of the Senate winner.
