But Peltola isn’t the only candidate creating headaches for Republicans.
Another man named Daniel J. Sullivan is also seeking the Senate seat, raising concerns that some voters could accidentally support the wrong candidate.
Now, the Trump administration wants a federal judge to intervene before any potentially disputed election results become official.
DOJ Sounds Alarm Over Two Candidates Named Sullivan
The Justice Department filed its lawsuit Thursday, arguing that Alaska’s unusual ballot situation could jeopardize the accuracy of the election.
The dispute involves incumbent Republican Sen. Dan S. Sullivan and Daniel J. Sullivan, a retired educator from Petersburg who has entered the race.
Although the two candidates have different backgrounds and political affiliations, their nearly identical names have become the focus of a fierce election controversy.
Federal attorneys contend that voters who intend to support the Republican incumbent could mistakenly cast their ballots for the other Sullivan.
In an election decided by a razor-thin margin, even a relatively small number of confused voters could potentially affect the outcome.
The administration is particularly concerned about a scenario in which Peltola defeats the incumbent by fewer votes than those received by Daniel J. Sullivan.
Under those circumstances, federal prosecutors want the state prevented from immediately certifying the results until the disputed votes can be examined.
The Justice Department has gone further than simply warning about possible voter confusion.
Its filing directly questions the motivations behind the second Sullivan’s candidacy.
“The sole purpose of his candidacy is to benefit the Peltola campaign by reducing the number of votes for Senator Sullivan,” Associate Attorney General Stanley Woodward Jr. argued in the filing.
That allegation has not been established in court, and Daniel J. Sullivan maintains that his decision to run was independent.
Nevertheless, the administration argues that the potential consequences deserve serious judicial scrutiny.
Alaska Supreme Court Already Rejected Republican Challenge
The controversy did not begin with the federal lawsuit.
Republicans previously attempted to prevent Daniel J. Sullivan from appearing on the ballot, arguing that his candidacy created an unacceptable risk of confusion.
However, the Alaska Supreme Court rejected that effort, allowing both candidates to remain in the race.
State election administrators subsequently adopted ballot descriptions intended to help voters distinguish between them.
The incumbent is identified as a Republican, while the other Sullivan appears without a political party designation.
Election officials believe those distinctions provide voters with important information when selecting their preferred candidate.
But the Justice Department’s latest action suggests federal officials remain unconvinced that those safeguards adequately address the problem.
Adding another layer of complexity is Alaska’s ranked-choice voting system.
Unlike traditional elections in which voters select just one candidate, Alaska allows voters to rank candidates according to preference.
That system could influence how votes for the two Sullivan candidates are ultimately counted and transferred during the tabulation process.
Whether the presence of two similarly named candidates actually changes the outcome remains uncertain.
Trump’s DOJ Wants Answers Before Certification
The administration’s lawsuit seeks a specific remedy rather than an immediate declaration that the election is invalid.
Federal prosecutors want judicial intervention if the incumbent loses by a margin narrow enough that votes cast for Daniel J. Sullivan could have made the difference.
Under that scenario, the Justice Department is seeking an examination of whether voters mistakenly selected the retired teacher when they actually intended to support the sitting senator.
That request raises complicated legal questions.
Determining what a voter intended after a ballot has been cast is not straightforward, particularly when election officials must also protect ballot secrecy and comply with established counting procedures.
The case also tests the limits of federal authority over elections traditionally administered and certified by individual states.
Attorney General Todd Blanche addressed concerns about federal interference during remarks to reporters Thursday.
“It is not DOJ’s intention to and it’s never our intention to improperly interfere with elections or the state certification process,” Blanche told reporters.
His comments underscore the administration’s position that its lawsuit is intended to protect the integrity of the election rather than override legitimate state authority.
Critics of the intervention, however, could argue that delaying certification based on speculative voter confusion would itself create uncertainty surrounding the results.
Ultimately, the federal court will have to determine whether the Justice Department has presented a sufficient legal basis for the extraordinary relief it seeks.
Senate Majority Could Hang in the Balance
The timing of the legal confrontation makes the dispute particularly consequential.
Alaska voters are preparing for the November 3 midterm elections, when the balance of power in Congress will be decided.
Republicans are working to preserve their Senate majority, while Democrats see competitive races such as Alaska’s as potential opportunities to gain ground.
Sullivan’s contest against Peltola has already drawn considerable attention because of the former congresswoman’s statewide political experience and the significance of the seat.
The emergence of another candidate sharing the incumbent’s name has introduced an unusual variable into an already competitive race.
For Republicans, the concern is that an avoidable ballot mix-up could become decisive if the election is extremely close.
For election administrators, the challenge is ensuring that every lawful vote is counted accurately without undermining established certification procedures.
The Justice Department’s filing does not itself suspend certification or establish that any voters have been misled.
A federal judge must first consider the administration’s arguments and decide whether intervention is legally justified.
And unless the election produces the kind of narrow result described in the lawsuit, the requested remedy may never become relevant.
Still, the legal battle guarantees that Alaska’s Senate contest will face additional scrutiny as Election Day approaches.
With control of the Senate potentially resting on a handful of competitive races, the administration is signaling that it intends to challenge circumstances it believes could compromise the outcome.
The central question now is whether the federal courts will agree that two candidates sharing the Sullivan name present a legally significant election problem—or conclude that Alaska’s existing safeguards are sufficient.
Either way, the controversy has added a dramatic new dimension to a Senate race that was already shaping up to be one of the most closely watched contests of 2026.
