Alaska Senate race features two candidates named Dan Sullivan

Alaska's pivotal U.S. Senate race features a highly unusual matchup as two candidates named Dan Sullivan advance to the November 2026 general election. Incumbent Republican Senator Dan S. Sullivan faces a challenge from Democrat Mary Peltola, who led the primary with 48.2% of the vote, and retired schoolteacher Daniel J. Sullivan Jr., a registered Republican running without party affiliation. Republicans fear the name similarity will split the GOP vote and hand the seat to Peltola, potentially deciding control of the Senate. The state's ranked-choice voting system may mitigate the spoiler effect, though historical data shows many voters exhaust their ballots without ranking backup choices.

Alaska Senate name confusion

• ▪The November 2026 Alaska U.S. Senate general election ballot will feature two candidates named Dan Sullivan: the Republican incumbent Senator Dan Sullivan and a retired schoolteacher named Dan J. Sullivan.
• ▪To differentiate the two same-named candidates on the ballot, the Alaska Division of Elections listed the challenger as Daniel J. Sullivan Jr. with no party affiliation, and the incumbent as Dan S. Sullivan, Republican and incumbent.
• ▪In the August 2026 Alaska all-party Senate primary, Democratic former Representative Mary Peltola led with 48.2% of the vote, followed by incumbent Republican Senator Dan Sullivan with 42.6%, and challenger Dan J. Sullivan with 2.5%.

Ranked-choice voting mechanics

• ▪Historical data from Alaska's 2022 and 2024 congressional elections shows that an average of 28% of voters did not rank a backup candidate, thereby exhausting their ballots when their top choice was eliminated.
• ▪Under Alaska's ranked-choice voting system, if no candidate wins a majority in the first round, the lowest-ranking candidates are eliminated, and their ballots are redistributed to voters' subsequent choices.

Republican vote-splitting fears

• ▪Allies of Senator Dan Sullivan have run advertisements emphasizing the senator's middle initial to help voters distinguish him from challenger Dan J. Sullivan.
• ▪Republicans fear that the presence of challenger Dan J. Sullivan on the ballot will confuse voters and siphon critical votes away from incumbent Senator Dan Sullivan in a race that could decide control of the U.S. Senate.
• ▪President Donald Trump endorsed incumbent Senator Dan Sullivan for reelection and publicly characterized the candidacy of Dan J. Sullivan as an attempt to trick voters.

Peltola Democratic challenge

• ▪National Democrats have invested millions of dollars to support Mary Peltola's campaign, as the party needs a net gain of four seats to secure a Senate majority.
• ▪Democratic former Representative Mary Peltola is challenging incumbent Senator Dan Sullivan to flip the seat in a state that Donald Trump won by 13 percentage points in 2024.

Ballot eligibility litigation

• ▪Republicans challenged Dan J. Sullivan's eligibility by pointing to Federal Election Commission filings showing a Daniel or Dan Sullivan in Petersburg, Alaska, donated $650 to ActBlue, including donations earmarked for Mary Peltola.
• ▪Challenger Dan J. Sullivan secured his spot on the ballot after the Alaska Supreme Court invalidated a decision by Alaska Division of Elections Director Carol Beecher, who had ruled him ineligible.
• ▪Republicans highlighted that the metadata of Dan J. Sullivan's campaign announcement document was tied to Amber Lee, a political consultant who has publicly supported Mary Peltola.
