Supreme Court Clears Path for Trump Mail-In Voting Restrictions

The Supreme Court of the United States ruled 6-3 to overturn a lower court injunction that had blocked an executive order by Donald Trump to tighten mail-in voting rules for the 2026 midterms. The order requires the Department of Homeland Security to compile lists of adult U.S. citizens by state and directs the United States Postal Service to deliver ballots only to individuals on those lists. The court did not rule on the legality of the order but determined that 23 Democratic-led states lacked standing because potential harms were conjectural.

Following the ruling, Democratic officials from 24 states and the District of Columbia, alongside voting rights groups, filed new federal lawsuits to block the resulting United States Postal Service rule. This rule establishes federal ballot-design requirements and mandates that states transmit voter information to the federal government. Plaintiffs argue the measure is unconstitutional and infringes on state election administration.

U.S. District Judge Indira Talwani briefly lifted a nationwide injunction to comply with the Supreme Court's decision but subsequently issued a temporary restraining order freezing the rule for two weeks. The Trump administration is currently appealing this freeze to the U.S. Court of Appeals for the First Circuit, maintaining that the regulations are necessary for election security.
