Democratic States Sue to Block Trump’s New USPS Mail-In Ballot Rules

Rhode Island Attorney General Peter Neronha labeled the policy an unlawful overreach, arguing it violates the U.S. Constitution’s clear mandate that states retain primary authority over election administration. The legal action arrives shortly after a federal judge in Boston lifted an injunction against the president’s March executive order, which had sought to restrict mail-in voting procedures under the guise of preventing fraud.

New York Attorney General Letitia James warned that the timeline for compliance is effectively impossible, noting that election officials would have mere weeks to redesign ballot envelopes, secure federal approval, and establish entirely new data-transmission systems before the 2026 midterms. Failure to meet these requirements could leave millions of Americans unable to return their ballots.

Observers see this move as part of a broader strategy to exert federal control over the 251-year-old agency. President Trump is currently attempting to fill four vacancies on the USPS Board of Governors with Republican nominees, a move that breaks the traditional practice of bipartisan appointments. Senator Gary Peters of Michigan has criticized the push, warning that such a shift threatens to transform the Postal Service into a partisan instrument for voter suppression.
