A super PAC involved in Alaska’s closely watched U.S. Senate race received substantial funding from progressive-linked organizations while spending millions of dollars in the state’s Republican primary, according to newly disclosed campaign finance records. The revelations are intensifying Republican accusations that outside groups are attempting to weaken Sen. Dan Sullivan’s reelection bid by exploiting confusion over a candidate who shares his name.

The group, Right for Alaska, has been at the center of controversy over retired schoolteacher Dan J. Sullivan, a Republican candidate whom critics have dubbed “Decoy Dan.” The challenger shares a name with incumbent Sen. Dan Sullivan, R-Alaska, who is running against former Rep. Mary Peltola, D-Alaska, in the Nov. 3 general election.

Federal campaign finance records show Right for Alaska received approximately $990,000 from the Sixteen Thirty Fund, a progressive-aligned nonprofit, along with millions in reported funding from Liberty Force Action Fund. Liberty Force Action Fund does not publicly identify its underlying donors. The organizations’ reported financial ties have prompted questions about who is financing efforts that could complicate the Republican incumbent’s campaign.

Both organizations list Thomas Datwyler as treasurer. Datwyler was previously identified as treasurer of former Rep. George Santos’ campaign, although he disputed having held that role. He did not immediately respond to a request for comment from the New York Post, which first reported the latest disclosures.

Republicans have argued that the similarly named candidate could confuse voters in a race where even a small shift in support could matter. Sen. Sullivan has President Donald Trump’s endorsement, while Dan J. Sullivan has acknowledged voting for Democratic presidential candidates in the past three elections and supporting Peltola in her 2022 and 2024 congressional campaigns.

The challenger has denied trying to mislead voters, describing himself as a moderate Republican. “My intention is not to trick people,” he said in an earlier interview.

Alaska election officials initially removed Dan J. Sullivan from the primary ballot over concerns about potential voter confusion, but the Alaska Supreme Court later reinstated him. Both men advanced through the state’s nonpartisan August primary and are set to appear on the November ballot.

Trump addressed the controversy during a campaign appearance in Wasilla last week, urging Alaskans to support the “real” Dan Sullivan. He accused Democrats of recruiting the namesake candidate and warned that the challenger’s 2.5% showing in the primary could make a difference in the general election.

The race is unfolding under Alaska’s ranked-choice voting system, which allows voters to rank candidates in order of preference. The latest RealClearPolitics polling average cited in the report showed Peltola at 49.5% and Sen. Sullivan at 47%, underscoring the narrow margins surrounding the contest.

The campaign finance disclosures do not, by themselves, establish that Democratic groups recruited Dan J. Sullivan or that he is deliberately trying to deceive voters. They do, however, add scrutiny to the role of outside spending in the race and to the possibility that a same-name candidate could affect the contest between the incumbent Republican and Peltola.
