Who’s Most Likely to Vote by Mail in 2026?

Mail-in voting has grown in the United States, but 2026 rules remain uncertain as lawsuits unfold. A federal judge paused USPS enforcement of new mail-ballot requirements after the Supreme Court allowed parts of Trump’s order to proceed, while USPS reports significant IT concerns about a new ballot-verification system. Pew Research Center findings show that 2024 mail voters skew older and more urban/suburban. With Trump’s push to curb mail voting and ongoing litigation potentially delaying changes, the handling of tens of millions of ballots and election administration could be substantially affected.
