Representative Mary Peltola and Senator Dan Sullivan are competing for an Alaska Senate seat in a race currently considered a tossup. The Economist electoral model estimates a 54% probability of victory for Peltola as the election approaches in November 2026.
Why it matters
The race is heavily influenced by Alaska’s unique political culture and the impact of federal policies on local industries like fisheries. Salmon stock concerns and high fuel costs remain central issues for residents across the remote state.
The Economist electoral model gives Mary Peltola a 54% chance of victory in the upcoming Senate race. This forecast accounts for a political environment where Donald Trump previously won Alaska by a 13-point margin.
The players
Mary Peltola
She is the incumbent Representative for Alaska who was first elected to the House of Representatives in 2022.
Dan Sullivan
He is the incumbent Republican Senator for Alaska who has served in the chamber since 2014.
Donald Trump
He is the current President of the United States who won Alaska by 13 points in the last presidential election.
Lisa Murkowski
She is a longtime Alaska Senator who famously secured her seat via a write-in campaign in 2010.
The details
Candidates are campaigning across a vast territory twice the size of Texas, utilizing Alaska’s system of non-partisan primaries and ranked-choice voting. Recent debates, including one held on Kodiak Island, have highlighted local concerns regarding the 5% reduction in the federal workforce and record-high rural fuel costs.
Timeline
2010: Lisa Murkowski won a write-in Senate campaign.
2014: Dan Sullivan was first elected to the Senate.
2022: Mary Peltola was first elected to the House of Representatives.
2025: Alaska lost nearly 5% of its federal workforce.
September 12, 2026: The first major Senate debate took place.
Political Context
Opponents of the incumbent often argue that the state’s non-partisan primary and ranked-choice voting system can skew results in unpredictable ways. This electoral framework remains a primary point of contention for those seeking to return to traditional partisan primary structures.
The outcome of this race will dictate which party controls the seat that oversees federal funding for the state's infrastructure and fishery programs. With rural fuel costs reaching $7.56 per gallon, voters are focused on how the next Senator will address federal employment declines and economic costs.
The takeaway
Alaskans are weighing the economic impact of federal policy against the backdrop of a highly competitive race. Voters should review the ranked-choice ballot structure to understand how their preferences will be counted in the final tally.
