(The Center Square) – Republicans are suing Nevada Secretary of State Francisco Aguilar, alleging the state needs to make voter rolls compliant with federal law.

The lawsuit, by the Republican National Committee and Nevada Republican Party, says five counties in the state have “inordinately high” rates of voter registration, three counties have more registered voters than adults over 18 years old, and two counties have rates over 90% registration.

Those discrepancies mean Nevada is “failing to make a reasonable effort to conduct appropriate list maintenance as required by the [National Voter Registration Act],” the lawsuit alleges.

“Election integrity starts with clean voter rolls, and that’s why the National Voter Registration Act requires state officials to keep their rolls accurate and up-to-date,” RNC Chair Michael Whatley said in a statement. “Nevada has universal mail voting and no voter ID requirement, which makes Secretary of State Cisco Aguilar’s failure to comply with the NVRA and provide accurate voter rolls all the more concerning.”

A spokesperson for Aguilar’s office told The Center Square he doesn’t have any new comment, but pointed to a January letter from the attorney general’s office disagreeing with the claims made about voter rolls in a December letter from the attorney representing the RNC.

“We write in response to your December 4, 2023 letter, in which you claim Nevada is not complying with the NVRA’s voter roll maintenance requirements, based on registration rates in eight Nevada counties,” the letter from the attorney general’s office said. “Based on more accurate data and applicable laws, we strongly disagree with your claim. If you have specific concerns related to Nevada’s NVRA maintenance requirements, please identify them so we can have an opportunity to respond accordingly.”

The RNC’s lawsuit asks for a declaratory judgment and injunction against the state.
