Summary

Alaska's Senate election will feature Republican Senator Dan Sullivan and Democrat Mary Peltola as the top two candidates. The key number is $18 million, which is the amount of money that Peltola has raised so far for her campaign, compared to Sullivan's $12 million. A second candidate with the same name, Dan J. Sullivan, a former teacher, is also on the ballot and is being investigated by federal prosecutors over allegations he may be part of a conspiracy to confuse voters. The investigation comes after a legal battle over his spot on the primary ballot, with both Peltola's and Senator Sullivan's campaigns denying any involvement with him.

Story summary

Dan S. Sullivan, a Republican senator from Alaska, will face off against Mary Peltola, a former Democratic congresswoman, in the state's Senate election this November. Both candidates advanced to the general election after the primary, which used ranked-choice voting and allowed the top four finishers to move on regardless of party affiliation.

The unusual aspect of this election is that there are two other candidates with the same last name as Senator Sullivan: Dan J. Sullivan, a retired teacher who ran as a Republican, and Daniel J. Sullivan Jr., a former employee of the US Forest Service who was listed on the ballot with no party affiliation. The latter candidate had initially sought to confuse voters by filing under his full name, but a court ruled in favor of allowing him to appear on the ballot.

Alaska's top-four primary system and ranked-choice voting have created a unique dynamic, with three candidates sharing the same last name competing against each other. This has led to accusations that Dan J. Sullivan is a "Democratic plant" trying to draw votes away from the incumbent senator and benefit Mary Peltola, who is also running for the seat.

The endorsement of Senator Dan S. Sullivan by Dan A. Sullivan, a former mayor of Anchorage, has added another layer to this complex election. With primary votes still being counted, Peltola leads with 48% of the vote, followed closely by Senator Sullivan at 43%. The outcome of this election is likely to have significant implications for control of the US Senate in the upcoming midterm elections.
