Supreme Court Hears Arguments on Whether Mail-In Ballots Can Count After Election Day
The case could affect laws in more than a dozen states ahead of the 2026 midterm elections
The justices are considering Watson v Republican National Committee, a challenge to a Mississippi state law brought by the Republican party in 2024. Mississippi allows mailed ballots to be counted if they arrive within five business days of election day, so long as they were postmarked by election day.
Fourteen states, Washington DC, and three US territories have similar laws that allow for late-arriving ballots to be counted. A ruling against Mississippi could invalidate these provisions across the country, potentially disenfranchising thousands of voters whose ballots arrive through normal postal delays.
The case has taken on heightened significance in a midterm election year, with both parties closely watching how the conservative-majority court approaches voting access questions.
Analysis
Why This Matters
A ruling that ballots must arrive by election day could reshape how millions of Americans vote, particularly in rural areas where postal service is slower. The decision will land just months before the 2026 midterms.
Background
Republicans have broadly pushed to tighten mail-in voting rules since 2020, arguing that election-day deadlines are necessary for timely results. Democrats contend that postmark-based deadlines ensure every validly cast ballot is counted.
What to Watch
The court's reasoning will signal how far the conservative majority is willing to go on voting restrictions ahead of a consequential midterm cycle.
