Peltola vs Sullivan: Can Alaska Deliver the Senate?

Alaska almost never decides the Senate. It is a small state, safely Republican at the presidential level, and it hasn’t sent a Democrat to the U.S. Senate since Mark Begich lost re-election in 2014. But 2026 is producing an unusual map. Republicans start with a 53-seat majority, defending a manageable set of incumbents while Democrats face structural problems in Georgia (open), New Hampshire (open), and Michigan (open). The realistic Democratic path to the majority requires flipping four seats out of a group that includes Maine, North Carolina, Ohio, Iowa, and Alaska. Two of those five are legitimately competitive on the fundamentals; Alaska is one of them.

After Tuesday’s primary, the race is not a curiosity. It is a serious contest with genuine national implications.

The primary, briefly

Former Rep. Mary Peltola (D) led incumbent Sen. Dan Sullivan (R) roughly 48% to 43% with 98% of precincts reporting on Wednesday afternoon. Both advance to the ranked-choice November general along with two other candidates — a second Republican unrelated to the incumbent, also named Dan Sullivan, is on track for a top-four slot, and the fourth spot remains too close to call between Democrat David Leslie and Republican Gerald Heikes.

Peltola’s five-point margin over the incumbent is the number that matters. Alaska has not seen a Democratic Senate candidate perform at that level in a first count since the 2008 Begich–Stevens race. (For the full primary breakdown, see our recap piece.)

Why Alaska is on the path to 51

Cook Political Report currently rates the Alaska Senate race a toss-up, alongside Maine, Michigan, and Ohio. Sabato’s Crystal Ball has a similar assessment. The Inside Elections rating is Tilt R. None of these are outlier calls: Peltola has led public polling most of the summer, and pre-primary internal polling from both parties reportedly showed the race within a couple of points.

If Democrats win Maine (Collins) and North Carolina (Cooper) — both of which they should — they need to pull two more out of Ohio, Iowa, and Alaska while holding Georgia and New Hampshire. That’s a difficult path even in a favorable political environment. But it exists, and Alaska is more likely than most people outside political operations realized six months ago to be one of those two.

Peltola’s general-election case

Peltola’s pitch is built on three durable pieces:

1. Local identity. She is Yup’ik, the first Alaska Native elected to Congress, from the Yukon-Kuskokwim Delta in western Alaska. Her policy platform is fisheries, subsistence rights, and the cost of living in rural Alaska (she likes to point out that a gallon of milk runs $17 in some villages). The word “progressive” doesn’t appear in her paid media. The word “Democrat” barely does.
2. Ticket-splitting proof. She won her House seat in 2022 as Trump carried Alaska by more than 10 points, then lost re-election in 2024 by only three points in a state Trump carried by 13. The gap between the presidential ballot and her own vote share is Democrats’ entire theory of the case.
3. Fundraising. She reported raising $18 million by the pre-primary deadline against Sullivan’s $8 million. That advantage — roughly 2 to 1 — is unusual for a Republican-held Senate seat.

Sullivan’s defense

Sullivan is a two-term senator, a former state attorney general, and a retired U.S. Marine Corps Reserve colonel. He won his last two elections comfortably. His campaign message centers on his record: federal appropriations for Alaska (Coast Guard, military, North Slope oil and gas), tax cuts included in the One Big Beautiful Bill Act, and support for the Trump administration on nomenclature and defense issues.

The vulnerabilities are real. The same One Big Beautiful Bill Act contains roughly $1 trillion in Medicaid cuts over the next decade — a policy that lands particularly hard in a state with high rural health-care costs. Peltola raised this repeatedly in her primary-night speech and it will be central to her fall messaging. Trump’s creation of the Department of Government Efficiency (DOGE) and its federal-employee firings are another vulnerability: Alaska has an unusually high per-capita federal workforce, and Sullivan’s votes to defund public media hit KTOO and the state’s rural stations hard.

Sullivan enters the general with a solid campaign, good name recognition, incumbency advantages, and $17 million in reserved Senate Leadership Fund airtime. He is a slight underdog on today’s numbers — but he has been an underdog before and won.

The ranked-choice math

Alaska’s general elections use instant-runoff tabulation. Voters rank the four candidates on the ballot. If no one wins a majority of first-choice votes, the last-place candidate is eliminated and their ballots are redistributed to whichever remaining candidate each voter ranked next. The process continues until someone clears 50%.

In 2022, ranked-choice worked in Peltola’s favor: she took first in the initial count and gathered enough transfers from the eliminated Republican (Sarah Palin) to win. In 2024, the transfers flipped and Begich beat her on the final tabulation.

This year the field is smaller and less complicated. The likely fourth-place finisher will be eliminated first (either Leslie or Heikes), and their share is tiny — likely under 2%. The consequential elimination will be the second Dan Sullivan, whose voters will presumably transfer overwhelmingly to the incumbent. That means Peltola effectively needs a majority of the two-way vote — not a plurality — to win. Given a five-point first-count lead in the primary, that is entirely plausible but not automatic.

The Decoy Dan wild card

Daniel J. Sullivan, a Petersburg Republican unrelated to the incumbent, has raised essentially no money and runs no active campaign. Alaska Republicans fought to keep him off the ballot; the state party dubbed him “Decoy Dan.” Trump personally warned Alaskans not to vote for the challenger. Both Sullivans will appear on the November ballot with full names.

Under ranked-choice, a voter who ranks the “wrong” Sullivan first still has that vote counted for the wrong candidate. There is no automatic correction. In a race that could be decided by a few thousand votes, a 2–3% share bleed from the incumbent to the decoy is not a hypothetical concern; it is arithmetic.

The primary result suggests roughly 2.4% of Republican primary voters selected the wrong Sullivan even after weeks of party messaging telling them not to. That share will probably shrink in the general, when turnout is broader and voters are more attentive — but it will not shrink to zero.

Money and ads

Both parties have reserved substantial airtime. The Senate Leadership Fund committed $17 million to defend Sullivan; the Senate Majority PAC committed $12 million to support Peltola. Total spending in Alaska’s Senate race is likely to end in the $60–$80 million range once candidate committees and outside groups are added — enormous for a state where the entire electorate is under 400,000 voters.

Expect a saturation air campaign. The last two months will feel to most Alaskans like there is no other race in the country.

Bottom line

Peltola is a slight favorite on today’s numbers. She has raised more money, outperformed the top of the ticket in her last two Alaska races, and started the general election with a five-point lead. Sullivan has incumbency, a substantial party spend behind him, and a state that gave Trump 13 points last year. The Decoy Dan complication cuts against Sullivan at the margin.

If Democrats need Alaska to reach 51, this race will be the reason they either get there or fall short. It is the closest thing 2026 has to a genuine coin-flip Senate election.
