LAS VEGAS — As many as 11,000 noncitizens are registered to vote in the crucial swing state of Nevada because Democratic Secretary of State Francisco “Cisco” Aguilar is ignoring his duty to keep voting rolls clean, a lawsuit alleges.

The Trump campaign, the Republican National Committee and the Nevada GOP filed suit Thursday against Aguilar in Carson City judicial district court,

A total of 6,360 individuals listed in the Nevada’s Department of Motor Vehicles “noncitizen file” were registered to vote in 2020 — and 3,987 of them cast a ballot in that year’s general election, the lawsuit says.

Republicans say state data show likely more than 11,000 noncitizens are registered to vote this year — and an estimated 3,700+ will cast a ballot in November’s presidential election.

Nevada became an “all mail-in” voting state in 2022 — registered voters are automatically sent ballots — though early-voting locations are opened to let people cast ballots in person. This year, 98.4% of primary ballots were mailed in

Republican Adam Laxalt lost his US Senate race to Democrat Catherine Cortez Masto by 8,000 votes in 2022 — roughly four votes per precinct.

Such close results have the GOP intent on purging rolls of ineligible voters.

Last month, Aguilar’s office designated nearly 140,000 voters — out of a state voter pool just under 2.4 million — as inactive, with the bulk, 116,322, in heavily Democratic Clark County, which includes Las Vegas.

But the GOP says Aguilar must do more to weed out noncitizens registered to vote.

“Any efforts to allow non-citizens to vote threatens the very foundation of our elections and diminishes the power of lawful voters across our state,” said Nevada GOP chair Michael McDonald. “This isn’t just a legal issue — it’s about protecting the rights of Nevadans and preserving the integrity of our elections.”

The state Democratic party — named in the lawsuit along with Aguilar and the Democratic National Committee — did not respond to The Post’s comment requests.

Aguilar’s office dismissed the claims, telling The Post there are “numerous safeguards” already in place. “Any claims of a widespread problem are false and only create distrust in our elections,” the office said.

“It is already against the law for noncitizens to vote in federal elections, and conspiracies of widespread fraud are baseless. Voting is safe, fair, and effective. We will fight this misinformation and beat Republicans in court and at the ballot box in November fair and square,” a DNC spokesperson told The Post.

“There is no doubt that there will be non-citizens on the voter rolls,” Christian Adams, president of the Public Interest Legal Foundation, a Virginia voter-integrity group, told The Post. But he said it’s doubtful any meaningful relief will be granted before Election Day.

Adams, whose group located Nevada voters who listed strip clubs, coffee shops and vacant lots as their residence addresses this year, said a genuine solution would involve changing the National Voter Registration Act to allow private parties to sue to get voting rolls purged of noncitizens.

And the Election Assistance Commission should permit state-specific rules for voter registration, something not currently allowed, he said.

The RNC said Friday it had compelled Minnesota — home state of Democratic VP nominee Gov. Tim Walz — to remove “more than 1,000 potentially ineligible voters, including non-citizens.” 

The GOP said Walz’s enactment of “automatic” voter registration at the DMV and the state’s “Driver’s License For All” policy enabled the placement of noncitizens on the state’s voter rolls

Those voters are now listed as “inactive” pending a review of each registration, the party said.
