In another major Supreme Court decision, justices ruled 5 to 4 to uphold a Mississippi law that allows mail-in ballots to be received up to five days after an election, as long as they’re postmarked by Election Day. A ruling overturning the law could have seen hundreds of thousands of voters disenfranchised in future elections due to postal delays, or because they live in remote, rural locations. A New York Times review of the 2024 election found at least 725,000 such ballots.

The ruling is a blow to President Trump, who has sought to limit who can vote by mail, while promoting conspiracy theories about mail-in ballots. In response, voting rights journalist Ari Berman wrote, “Every major study has shown that mail-in voting is safe and secure, but the fact that four justices signed on to Trump’s crusade to get rid of mail-in ballots is highly disturbing and could embolden the president to attempt to take even more drastic steps to make it harder to vote.”
