Supreme Court rules states can count late-arriving mailed ballots, rejecting Trump-led challenge

The Supreme Court ruled that states can count mailed ballots arriving after Election Day if postmarked by Election Day, rejecting a Republican-led challenge. The decision preserves laws in over half the states and the District of Columbia, avoiding last-minute changes to ballot rules before the 2026 midterms. The case originated in Mississippi, where a federal appeals court had previously struck down a law allowing ballots to arrive within five business days of the election.
