Should Trump’s new mail-in voting restrictions apply to the 2026 midterms?

Trump’s administration says new USPS ballot-mail requirements will deter fraud. States, civil-rights groups and some justices dispute their authority and timing. The case asks whether mandatory enforcement should proceed for the November 2026 election.

Claim in dispute

Mandatory USPS ballot-mail requirements are lawful postal controls and should be enforced for the November 2026 election.

Case period:

Published by The Dispute Index editorial teamPublished Updated

Donald TrumpUnited States Postal Service

Overview

The conduct examined is implementing and enforcing the mandatory USPS ballot-mail requirements for elections on or before November 3, 2026. Support for a later or different postal rule is a separate question. The final rule excludes return ballot mail from the outgoing verification process and says USPS does not determine voter eligibility. Its 90-day pre-mailing notice is optional. The September 14 Supreme Court decision denied emergency relief from the preliminary injunction; the broader legal challenge remains distinct from this election’s rollout.
