Democratic Senate candidate Mary Peltola made last-minute changes to her campaign staff just days before Alaska’s primary election on August 19, 2025, dismissing a senior aide, replacing her campaign manager, and terminating two veteran contractors.
The incumbent Republican senator, Dan Sullivan, is defending his seat in a competitive race that could influence control of the U.S. Senate. Peltola, who served one term in the U.S. House, is the Democratic Party’s strongest challenger in Alaska’s Senate race, according to recent polling.
Campaign Shake-Up
Peltola’s campaign announced the departures of Elisa Rios, a longtime adviser who managed her previous congressional campaigns and served as her Senate campaign manager, as well as a deputy campaign manager. The changes come amid reports of financial backing for Peltola’s campaign, which has mounted a strong challenge to Sullivan’s reelection bid.
The campaign did not provide a detailed explanation for the staffing changes. However, Peltola recently distanced herself from former Vice President Kamala Harris, who had been raising funds for Peltola’s political action committee. Harris’s involvement was seen as potentially unhelpful in a conservative-leaning state, and Republicans criticized the association.
The Senate Race Landscape
The Senate race features two Republican candidates named Dan Sullivan—incumbent Sen. Dan S. Sullivan and challenger Dan J. Sullivan, a retired fifth-grade teacher. The Alaska Division of Elections initially sought to remove Dan J. Sullivan from the ballot, alleging his candidacy was not in good faith and aimed to confuse voters. A lawsuit followed, and the Alaska Supreme Court ruled in late June to keep him on the ballot under the state’s nonpartisan top-four primary system.
President Donald Trump has accused Democrats of “trickery” over the candidate with the same name, and the Justice Department confirmed it was investigating the matter. The Trump campaign and other Republicans have framed Dan J. Sullivan’s candidacy as an attempt to split the Republican vote.
Polling and Competitiveness
Recent polling indicates the race is highly competitive. A survey by Alaska Survey Research conducted August 2–5, 2025, showed Peltola leading Sullivan 51% to 49% among likely voters. Political analysts note that while Alaska has historically favored Republicans in presidential elections, the state has elected Democrats and independents to other offices, including former Sen. Mark Begich and independent Gov. Bill Walker.
Peltola’s campaign has emphasized her past statewide victory in 2022, when she became the first Indigenous member of Congress and the first woman to represent Alaska in the House. Sullivan’s campaign has countered that her 2022 win was an exception unlikely to repeat in a Senate race.
Primary Mechanics and Implications
Alaska’s top-four primary system allows up to four candidates from any party to advance to the general election, regardless of party affiliation. This means it is possible for both Sullivans and Peltola to appear on the November ballot. The primary outcome will determine which candidates move forward in a race that could determine Senate control in the next Congress.
The Alaska Division of Elections, overseen by Republican Lt. Gov. Nancy Dahlstrom, initially ruled against Dan J. Sullivan’s candidacy, but the court’s decision ensures he remains on the ballot. The state’s election system has drawn national attention due to its unique structure and the potential for multiple candidates from the same party to advance.
Background: The Two Dan Sullivans
Incumbent Sen. Dan S. Sullivan, a two-term Republican senator endorsed by Trump, faces a primary challenge from Dan J. Sullivan, who describes himself as a pragmatic Republican. The incumbent has dismissed his challenger as a “sham” candidate planted by Democrats to confuse voters, while Dan J. Sullivan has framed his campaign as a grassroots effort to offer an alternative to the establishment.
The presence of two candidates with the same name has sparked legal and political disputes, with allegations of voter confusion and potential interference. The Justice Department’s involvement underscores the high stakes of the race and the scrutiny surrounding the unusual circumstances.
What’s Next
The primary election on August 19, 2025, will determine which candidates advance to the general election in November. Polling suggests the race remains too close to call, with both Peltola and Sullivan campaigning aggressively in the final days. The outcome could have significant implications for the balance of power in the U.S. Senate.
