Supreme Court upholds state law on late mail-in ballots

The Supreme Court upheld a Mississippi law allowing mail-in ballots postmarked on Election Day to be counted up to five days later, rejecting a Republican National Committee challenge. The 5-4 decision emphasized federal law does not require ballots to be received by Election Day, with Justice Amy Coney Barrett writing the majority opinion. The ruling impacts 30 states and Washington, D.C., ahead of the 2026 midterms.
