The lawsuits have been flooding in for months from the Republican National Committee—now part of the family firm under the co-chairmanship of Trump’s daughter-in-law—and allied groups. The list includes lawsuits to purge voting rolls, disqualify significant numbers of absentee and mail ballots, and to make it easier for local officials to refuse to certify elections.

On the other side, a coalition of nonpartisan national voting rights groups—including the Campaign Legal Center, Common Cause, the NAACP Legal Defense Fund, the American Civil Liberties Union, the Brennan Center for Civil Rights, the Lawyers’ Committee for Civil Rights, the Fair Elections Center, and the Southern Poverty Law Center—have been coordinating and preparing for two years to protect people’s right to vote and to have their vote counted.
