Supreme Court Allows Trump Mail-In Voting Restrictions to Proceed

The Supreme Court of the United States ruled 6-3 on August 24, 2026, to lift a lower-court injunction that had blocked a March executive order from President Donald Trump. The order, titled Ensuring Citizenship Verification and Integrity in Federal Elections, directs the United States Department of Homeland Security to compile citizenship lists and mandates that the United States Postal Service refuse delivery of ballots to individuals not on those verified lists. The majority held that a coalition of 23 Democratic-led states and Washington, D.C., lacked standing because their claims of harm were premature and speculative.

Justice Ketanji Brown Jackson issued a sharp dissent, arguing the ruling needlessly injects chaos and uncertainty into the November 3 midterm elections. While the ruling removes a procedural hurdle, it is not a final determination on the order's legality. Furthermore, a separate nationwide injunction issued by U.S. District Judge Indira Talwani remains in place, blocking the United States Postal Service from enforcing its final 95-page rule, which includes strict barcode and logo formatting for ballot envelopes.

Democratic governors and attorneys general from states including California, New York, and Oregon condemned the move as an unconstitutional federal intrusion into state-run elections. Conversely, Republican officials praised the decision as a victory for election integrity. In a related effort to secure the agency's direction, Donald Trump nominated four Republicans to the Postal Service Board of Governors, breaking the tradition of bipartisan pairs.
