Federal Courts Clear Way for Trump's Mail-In Voting Restrictions Ahead of 2026 Midterms
U.S. District Judge Indira Talwani on August 26, 2026 vacated a nationwide injunction she had issued that blocked the U.S. Postal Service from carrying out President Trump's executive order restricting mail-in voting, handing the administration a temporary win in the legal fight over ballot access ahead of the 2026 midterms.

A preliminary injunction is a court order that temporarily stops a policy from taking effect while a lawsuit plays out. Talwani's order had been one of two such injunctions preventing enforcement of the executive order. On August 11, 2026, Talwani issued a preliminary injunction barring the Trump administration from implementing the order, finding it likely unconstitutional. ACLU That ruling followed an earlier June injunction from Talwani that applied only to the 23 mainly Democratic-led states and Washington, D.C., that sued over the order. The U.S. Supreme Court had already halted that narrower June injunction on procedural grounds. NPR
Two days before Talwani's August 26 vacatur, on August 24, 2026, a divided Supreme Court lifted the second of the two injunctions, clearing the Trump administration to move forward with the executive order restricting mail-in voting ahead of the midterm elections. New York Times; PBS NewsHour The Court's ruling addressed a procedural issue and did not weigh on whether the executive order itself is legal.

The executive order, issued in March 2026, directed USPS to publish a final rule for federal ballot mail establishing new design requirements for mail-in ballot envelopes. The rule also included a plan to deliver mail-in ballots only to individuals on lists of absentee voters that states would be required to turn over to the Postal Service. Federal Register
The legal battle has moved through multiple tiers of the federal judiciary with unusual speed. Talwani's August 11 injunction was a renewed barrier after earlier proceedings. The Supreme Court's August 24 order lifted the injunction that had been blocking enforcement, and Talwani's August 26 vacatur of her own nationwide ruling removed the remaining judicial obstacle at the district court level. The sequence means that, as of August 26, both injunctions against the USPS final rule have been dissolved or lifted, at least temporarily. NPR
The order faces continued legal challenges. Lawsuits filed by Democrats, voting rights groups, and two dozen mainly Democratic-led states are still proceeding through the courts. NPR
The broader context here is that the Supreme Court's August 24 intervention was procedural, not merits-based. The justices have not ruled on whether Trump's executive order restricting mail-in voting is constitutional. That question remains unresolved as the underlying litigation continues. What the Court did was lift a judicial stay on enforcement, allowing the administration to proceed while the legal challenges play out. Talwani's subsequent vacatur of her nationwide injunction on August 26 removed the second barrier, but both actions turned on procedural posture rather than a definitive ruling on the order's legality.
The stakes are direct and practical. The USPS final rule's requirements, including new envelope design standards and the absentee-voter-list provision, could affect how states administer mail-in voting for the November 2026 midterms. States that do not comply with the design and list-sharing requirements risk having USPS decline to deliver mail-in ballots under the rule's terms. Litigants challenging the order argue it imposes federal conditions on a voting mechanism that states have historically administered under their own authority.
Prior appellate litigation on mail-in voting procedures has addressed related but distinct questions. The Third Circuit in Bognet, No. 20-3214, examined whether voters could have cast mail-in ballots before Election Day given USPS delivery timelines. The Seventh Circuit, in a Democratic National Committee case, upheld an order permitting replacement absentee ballots to be transmitted electronically to domestic civilian voters. In Common Cause Indiana, plaintiffs challenged Indiana's refusal to permit no-excuse mail-in absentee voting during the COVID-19 pandemic. A Kansas federal district court case addressed canvassing of mail-in ballots before Election Day and treatment of ballots received within two days of Election Day. An Eastern District of Michigan case involved plaintiffs seeking to halt absentee ballot processing until an election inspector was present. None of those prior cases addressed the specific mechanism at issue here: a federal executive order directing USPS to impose design and delivery conditions on mail-in ballots.
The litigation path forward will test whether the executive order's requirements survive a merits ruling. The Supreme Court's procedural disposition in August removed the injunctions but left the constitutional question open. Talwani's August 11 finding that the order is likely unconstitutional remains part of the record, even though her nationwide injunction has now been vacated. How the district court and, eventually, the appellate courts treat that finding on the merits will determine whether the USPS final rule stays in effect for the midterm cycle and beyond.
