Supreme Court Mail Ballots

The U.S. Supreme Court is set to hear arguments over a Mississippi law that allows counting late-arriving mail ballots after Election Day. The high court on Monday will hear from Republicans and Libertarians who sued the state, arguing that federal Election Day statutes envision a single day for casting ballots, which would mean that grace periods for receiving mail ballots aren't allowed. The practice is a frequent target of President Donald Trump and allies who argue it delays vote tallies and leads to suspicions about the results, even though there is no evidence of fraud in late-arriving ballots. Grace periods for all mail ballots are allowed in 14 states, with an additional 15 granting extra time for military and overseas ballots to arrive.

The Supreme Court is taking up a case from Mississippi over whether states can count late-arriving mail ballots, a target of President Donald Trump. The outcome of the case being argued Monday could affect voters in 14 states and the District of Columbia, which have grace periods for ballots cast by mail. An additional 15 states that have more forgiving deadlines for ballots from military and overseas voters also could be impacted. A ruling is expected by late June, early enough to govern the counting of ballots in the 2026 midterm congressional elections. State and big-city election officials have warned of “confusion and disenfranchisement” if states are forced to make quick changes. The court challenge is part of Trump’s broader attack on mail balloting.
