It was another good day for voting integrity today as the Supreme Court heard arguments about Mail-In Voting and specifically whether or not mail-in ballots arriving after Election Day could be counted as valid. While no official decision has yet been reached, it appeared likely that the Court would be making some very big changes to the current process, possibly even reaching a 6-3 decision based on how the questioning was going. HOLY CRAP!

The court heard arguments in a case from Mississippi that could also affect voters in 13 other states and the District of Columbia, which have varying grace periods for mail ballots. The decision may also impact an additional 15 states that have more forgiving deadlines for ballots from military and overseas voters. A ruling is expected by late June, early enough to govern the counting of ballots in the 2026 midterm congressional elections. What to know: The case: The issue at hand is whether federal law sets a single Election Day that requires ballots to be both cast by voters and received by state officials. The court challenge is part of a broader attack by Trump on most mail balloting, which he has said breeds fraud despite strong evidence to the contrary and years of experience in numerous states. The justices: Several conservative justices, including Samuel Alito and Brett Kavanaugh, voiced some of Trump’s complaints with questions about the prospect of rigged elections or fraudulent late-arriving ballots. The court’s liberal justices, conversely, indicated they would uphold state laws with post-Election Day deadlines, largely as a matter of upholding state rights over their own voting rules. The implications: If the court strikes down the grace periods, it’ll leave some states and their voters scrambling to adjust with only a few months before absentee ballots are sent out this fall.
