The Republican National Committee (RNC) filed two new anti-election lawsuits this week in Michigan and North Carolina.

On Thursday, the RNC sued the North Carolina State Elections Board, alleging that it failed to remove non-citizens from the voter rolls.

State law does not allow noncitizens to vote in elections or serve on jurors. A new law requires all county clerks in North Carolina to record when a person called for jury duty asks to be excused from jury duty because they are not a U.S. citizen and send that person’s information to the state Board of Elections. The law then requires the board to remove the person from the voter rolls if they are registered to vote.

The RNC’s lawsuit alleges that the state board failed to follow the new law’s requirements to remove noncitizens recorded by county clerks from the state’s voter rolls. The lawsuit also alleges that the board denied the RNC’s request to see copies of the state’s voter rolls and other records used to maintain the voter rolls, in violation of the North Carolina Public Records Act.

The RNC is asking a North Carolina court to remove all noncitizens from the state’s voter rolls and require the panel to provide them with copies of the state’s voter registration records.

This lawsuit is the latest in a series of legal efforts challenging the way voter rolls are maintained at the state and county levels and seeking to purge millions of registered voters from the rolls nationwide. According to Democracy Docket’s litigation tracker, there are at least 21 active anti-voting lawsuits in 16 states that seek to purge voter rolls in some form.

A recent investigation by the Democracy Docket has identified at least eight right-wing groups — including larger ones like the Election Integrity Network and True the Vote, and smaller grassroots groups like Wisconsin’s North of 29 — that are working to remove millions of registered voters from their state’s voter rolls. These efforts are taking the form of lawsuits, such as those filed earlier this month by the right-wing United Sovereign Americans in Florida and Ohio, and door-to-door campaigning, such as the one the Pigpen Project is conducting in Nevada.

The RNC’s lawsuit is also part of a larger right-wing effort to spread misinformation about noncitizens voting in federal elections. Earlier this year, Republicans in Congress introduced a nationwide bill that would ban noncitizens from voting in federal elections — a practice that has been banned since the mid-1990s. Since then, GOP lawmakers across the country have been spreading the false narrative that noncitizens are voting en masse in federal elections — and it could have implications for the upcoming presidential election.

On Friday, the RNC filed another lawsuit in Michigan, accusing the Detroit Election Commission of violating state law by hiring more Democratic than Republican poll workers for the upcoming election.

Under state law, election commissioners are responsible for appointing as many election inspectors from each major political party as possible in each precinct. The RNC’s lawsuit alleges that 300 of Wayne County’s 335 precincts do not employ equal numbers of Republican and Democratic election inspectors. The lawsuit also alleges that Detroit has hired only 310 Republican election inspectors, compared to over 2,300 Democratic ones.

The lawsuit alleges that the chairman of the Wayne County 12th Congressional District Republican Committee submitted a list of 675 names of Republicans seeking to serve as election inspectors to the Detroit Elections Committee, but the committee appointed only 52 of the proposed names as election inspectors.

The RNC is asking the court to order the Detroit Election Commission to take steps to ensure it hires an equal number of Republican and Democratic election inspectors.
