Supreme Court Lets Trump’s Mail Voting Limits Stand for November 2026
On August 24, 2026, the Supreme Court allowed Trump’s mail-in voting restrictions for November’s midterms.
Why it matters: Election law and compliance teams must watch evolving federal-state mail voting rules that affect legal challenges and ballot delivery procedures before the midterms.
- Supreme Court ruled 6-3 on August 24, 2026, lifting a lower court's block on Trump’s mail-in voting restrictions.
- The ruling lets DHS create a federal citizenship list; USPS must deliver mail ballots only to people on it.
- 24 states and Pennsylvania quickly renewed lawsuits claiming the USPS rule violates state authority over elections.
- Pennsylvania’s Governor Josh Shapiro confirmed the state will keep its mail voting unchanged for the 2026 election cycle.
On August 24, 2026, the U.S. Supreme Court, in a 6-3 decision, allowed key portions of former President Trump’s executive order restricting mail-in voting to go into effect for the November midterm elections. The decision lifts a lower court injunction, enabling the Department of Homeland Security (DHS) to compile a federal citizenship registry and directing the U.S. Postal Service (USPS) to deliver mail ballots solely to individuals on that list. This changes established mail voting procedures nationwide. ABC News covers the ruling and its immediate effects.
In response, 24 states and Pennsylvania have renewed lawsuits opposing the USPS’s final rule implementing these restrictions. They argue the rule oversteps states’ constitutionally granted authority to regulate elections. Washington State has filed an additional lawsuit emphasizing concerns about federal intrusion into state-controlled election administration. Axios provides details on these ongoing legal challenges.
Justice Ketanji Brown Jackson dissented, warning the ruling endangers electoral fairness immediately before ballots are mailed, calling the situation a "Kafkaesque nightmare." Justice Sonia Sotomayor noted the Court did not rule on the order's legality and did not affirm federal authority to regulate state elections. Their dissent reflects judicial uncertainty as the nation prepares for voting. See coverage by The Daily Beast and The Week.
Despite the ruling, Pennsylvania Governor Josh Shapiro confirmed the state will continue its existing mail voting procedures for the 2026 cycle, providing some local certainty. At the same time, experts note that about one-third of Americans who use mail-in voting face increased uncertainty with this new process, with vulnerable voters such as seniors and rural residents disproportionately affected. Election law experts like David Becker highlight potential reliability issues as states like North Carolina prepare to mail ballots starting September 4. Axios reports on these concerns.
Legal professionals involved in election law, compliance, and voting administration should monitor further litigation and federal-state tensions over mail ballot distribution. These developments underscore the evolving legal landscape ahead of critical November elections.
By the numbers:
- 6-3 Supreme Court vote — decision on August 24, 2026
- 24 states plus Pennsylvania — parties suing against USPS mail ballot rule
- September 4, 2026 — North Carolina begins mailing ballots
Yes, but: While the Supreme Court allowed the mail-in voting restrictions to proceed, the justices did not rule on the legality of the underlying executive order; ongoing lawsuits continue to challenge the federal government's intrusion into state-controlled election administration.
What's next: Further lawsuits are advancing in federal courts as states continue to contest the USPS mail ballot rule and federal citizenship list ahead of November 2026.
