Supreme Court Case Could Reshape Mail Ballot Grace Periods Nationwide

The U.S. Supreme Court is set to hear arguments in the case of Watson v. Republican National Committee, which challenges the legality of mail ballot grace periods in several states. This case could significantly impact voting procedures across the nation, particularly affecting the 14 states that currently allow ballots postmarked by Election Day to be counted if received later.

The lawsuit, initiated by the Republican National Committee and the Libertarian Party of Mississippi against Mississippi Secretary of State Michael Watson, argues that federal Election Day statutes mandate a single day for casting and counting ballots. They contend that allowing ballots to arrive after Election Day undermines election integrity. Conversely, supporters of grace periods assert that states have the constitutional authority to establish their own voting rules, which include accommodating mail-in ballots that may arrive late due to postal delays.

If the Supreme Court rules against mail ballot grace periods, it could disenfranchise voters, particularly in rural areas and those relying on mail services, such as Alaska. The implications extend to military and overseas voters, who often depend on extended deadlines to ensure their ballots are counted. A November 2025 Brookings Institution study indicated that mail voting fraud is exceedingly rare, with only four cases per 10 million ballots, suggesting that grace periods are essential for maintaining voter access rather than enabling fraud.
