Today, the Court ruled 5–4 in Watson v. Republican National Committee that federal Election Day statutes do not prevent states from counting mail ballots that are postmarked by Election Day but arrive afterward. The decision preserves mail ballot grace periods in 14 states and D.C. ahead of the 2026 midterms.

The ruling affirms a principle that voting rights organizations, election administrators, and bipartisan advocates urged the Court to recognize: Election Day is the deadline for casting a ballot, not for when that ballot must physically arrive. Voters who follow their state’s rules should have their votes counted.

Our Mail Ballot Receipt Deadlines Democracy Map tracks this policy across all 50 states and D.C. A ruling in this case overturning these grace periods would have upended rules for voters across the country with just months until the midterm elections.

Military and overseas voters, older voters, voters with disabilities, and rural communities rely disproportionately on mail voting — and are most vulnerable to mail delays beyond their control. Today’s decision protects those voters.

But challenges to mail voting aren’t over. Multiple executive orders targeting mail voting are currently being challenged in court, and voters in a number of states will face new restrictions this November. Track these developments in real time through our Democracy Maps.
