Supreme Court Affirms State Laws for Mail-In Ballot Postmark Grace Periods

In a 5-4 ruling on *Watson v. RNC*, the Supreme Court has upheld Mississippi's law permitting mail ballots postmarked by Election Day to be counted up to five business days later. This decision clarifies that such state provisions do not conflict with federal law regarding a single Election Day, focusing on the voter's action date rather than receipt date. The ruling reverses a Fifth Circuit decision and affects similar laws in 14 states and Washington D.C.
