Cook Political Report shifts Alaska Senate race to toss-up

A national election handicapper just moved Alaska's Senate race into its most competitive category — and unlike a campaign's own poll, this one's worth paying attention to, with a few caveats.

The Cook Political Report shifted the Sullivan–Peltola race from "Lean Republican" to "Toss-up" on July 1, a move that brightens Democrat Mary Peltola's odds against Republican Sen. Dan Sullivan. Cook matters here in a way a campaign press release doesn't: it's an independent, nonpartisan forecaster whose ratings political professionals across both parties actually track, and it doesn't have a candidate to sell. When Cook calls a red-leaning state's Senate seat a toss-up, that's a signal, not spin.

The rating rests on real polling, not vibes. A New York Times/Siena College survey released the same day put Sullivan at 47 percent and Peltola at 45 — a two-point gap inside the margin of error. That's the strongest evidence, because Times/Siena is an independent, high-quality pollster with no stake in the outcome. Anchorage pollster Ivan Moore's Alaska Survey Research has shown Peltola leading by five in its two most recent polls, though Moore's numbers tend to run more favorable to Democrats than other surveys, so they're worth treating as one data point rather than the headline.

The usual Alaska caveat applies, and it's a real one. National ratings can overstate how competitive Democrats truly are here — this is a state that leans Republican in federal races and has repeatedly disappointed Democrats who looked strong on paper. A toss-up rating means genuinely up for grabs, not favored.

Two things make the seat matter beyond the math. Peltola made history in 2022 as the first Alaska Native elected to Congress, and her presence in the race keeps subsistence rights, resource development, and federal-tribal relations near the center of how the Senate seat gets contested. And Alaska's voting system adds a twist a close race can turn on: under the top-four primary and ranked-choice general, candidates compete for second-choice votes across party lines, so how those preferences consolidate in November could decide a race this tight.
