ALASKA — Mary Peltola is a Democratic candidate in the Alaska U.S. Senate election, challenging incumbent Republican Senator Dan Sullivan. Sullivan is seeking a third term in the U.S. Senate.

The campaign has drawn national attention following a fundraising email sent by former Vice President Kamala Harris urging support for Peltola’s Senate campaign and her Fight for the People PAC. Harris wrote that "Alaska is a must-win Senate seat for Democrats to retake control of the Senate." She added that "if there’s anyone who can flip Alaska and secure the Senate majority for Democrats – it’s Mary. But she cannot do it alone." Harris stated that "when we all stand behind Mary, we can give her the boost she needs to overcome their spending and organize across Alaska."

Peltola’s campaign did not approve the fundraising email and does not seek Harris’s endorsement. A campaign spokeswoman said Mary isn’t seeking endorsements from anyone from the Lower 48 — her focus is and always will be Alaska. This distance reflects earlier political choices, as Peltola did not endorse Harris in the 2024 presidential election. Harris lost Alaska to Donald Trump by 14 percentage points in that election, while Trump won the state by 13 percentage points overall.

National Republican Senatorial Committee Spokesman Nick Puglia criticized the connection between the two Democrats. "Mary Peltola is an ineffective radical leftist who worked hand in hand with Kamala Harris to put Alaska last, so it’s no surprise that Harris is backing Peltola," Puglia said.

The race features distinct policy platforms, with Peltola campaigning under the slogan "Fish, Family, and Freedom." She advocates for banning factory trawling and reducing bycatch in Alaska fisheries. "As someone who grew up salmon fishing on the Kuskokwim River with my father, I know firsthand that fish is more than food—it's central to Alaskans' way of life," Peltola said. She stated that she will fight tooth and nail to restore our fisheries to abundance, and that means doing whatever it takes to ban factory trawling and reduce bycatch, deliver relief for Alaska fishermen and communities that are suffering the fallout of fishery collapse, and save our fish. Peltola added that she will stand up to anyone—including the factory trawling lobby and Lower 48 special interests—to fix the rigged system in D.C. and put Alaska first.

Bycatch remains an issue in the state. In 2026, trawlers caught nearly 22,000 Chinook salmon as bycatch in Alaska. To protect salmon populations, Alaska has implemented a seven-year fishing moratorium on the Yukon River. Public opinion appears aligned with Peltola’s stance, as a 2025 Data for Progress survey found that a majority of likely Alaska voters support a ban on trawling.

Sullivan introduced a bill in June 2026 to reduce bycatch, though Peltola introduced a similar bycatch reduction bill during her time in the House of Representatives which Sullivan did not support. Campaign finance records show Sullivan has received nearly $280,000 in contributions from the trawling industry. Trident Seafoods is one of Sullivan’s largest contributors. The company paid $2.5 million in 2011 to resolve Clean Water Act violations and was fined $300,000 in 2018 for underwater piles of fish by-product near its processing facilities.

Peltola brings prior legislative and judicial experience to the race. She served as Alaska’s at-large U.S. Representative from 2022 to 2025 after winning the seat in 2022. She lost her 2024 reelection bid for the U.S. House by fewer than three percentage points.

Before her congressional service, Peltola previously served as a judge on the Orutsararmiut Native Council's tribal court and as executive director of the Kuskokwim River Inter-Tribal Fish Commission. As of 2026, Peltola is the most recent Democrat to have won or held statewide office in Alaska. Her platform also includes support for 12-year term limits for members of Congress, overturning the Citizens United Supreme Court decision, and banning lawmakers from trading stocks.

Voters will head to the polls for the Alaska Senate primary on August 18. Under state rules, the top four vote-getters in the primary will advance to the November general election. Alaska has not elected a Democrat to the U.S. Senate since 2008.

Why It Matters

The outcome of this election could determine the balance of power in the U.S. Senate, as indicated by Harris’s assertion that the state is a must-win for Democrats. Polling data reflects the tight nature of the contest, with an August 2026 Alaska Survey Research poll showing Peltola with 50.8 percent and Sullivan with 49.2 percent in the final round of ranked-choice voting. An earlier June 2026 New York Times/Siena College poll showed Sullivan with a two-point lead in the initial round, with five percent of respondents undecided. The Cook Political Report and Sabato's Crystal Ball classify the race as a toss-up.

The campaign shows broader debates over resource management and corporate influence in Alaska politics. Peltola’s background in tribal fisheries management contrasts with Sullivan’s legislative record and industry contributions. The race also tests the viability of Democratic candidates in a state that has trended Republican in recent federal elections, including the 2024 presidential race where Trump secured a double-digit victory margin.
