Courts battle over Trump administration's mail-in ballot restrictions ahead of midterms

A legal battle intensifies over President Trump's March 2026 Executive Order restricting mail-in voting. The Supreme Court ruled 6-3 on August 24, 2026, that a multi-state challenge was premature, clearing the U.S. Postal Service to finalize its 95-page rule on August 26. The rule forces states to upload voter data to a federal portal and use approved envelopes. While Judge Indira Talwani temporarily blocked the rule again on August 27, state officials warn of severe pre-election chaos.

USPS mail-in ballot rule

• ▪Under the finalized U.S. Postal Service rule, postal employees must scan ballot envelopes to verify they are registered in the federal portal, and non-compliant mailings will be returned to election officials.
• ▪The U.S. Postal Service finalized a 95-page rule on August 26, 2026, requiring state and local election officials to submit mail-in voters' names and addresses to a new federal portal.
• ▪The finalized U.S. Postal Service rule exempts U.S. military and overseas voters mailing ballots from outside the United States, and applies only to general elections.
• ▪The finalized U.S. Postal Service rule mandates that election officials submit ballot-envelope designs to the agency for review and use unique Intelligent Mail barcodes.

Trump mail voting restrictions

• ▪President Donald Trump has repeatedly blamed mail-in voting for widespread electoral fraud, despite having voted by mail himself in Florida's primary in August 2026.
• ▪The Trump administration's March 2026 Executive Order specifies that state election officials could face criminal prosecution if they do not comply with the federal demands.
• ▪President Donald Trump issued an Executive Order in March 2026 directing federal agencies to restrict mail-in voting and establish state citizenship lists to monitor voter rolls.

Supreme Court litigation decisions

• ▪The Supreme Court ruled 6-3 on August 24, 2026, to lift a lower court's June injunction against President Donald Trump's Executive Order, stating the initial lawsuit was premature.
• ▪U.S. District Judge Indira Talwani vacated her nationwide preliminary injunction on August 26, 2026, but subsequently issued a new 14-day temporary restraining order blocking the finalized rule on August 27, 2026.
• ▪The Supreme Court's August 24, 2026, ruling did not address the constitutionality or legality of President Donald Trump's Executive Order, leaving it open to future challenges.

State implementation challenges

• ▪Hawaii Chief Election Officer Scott Nago stated that the U.S. Postal Service rule would force the state to discard previously ordered envelopes at a cost of over $79,000.
• ▪Arizona Secretary of State Adrian Fontes characterized the U.S. Postal Service rule as a logistical nightmare, noting that election planning and envelope purchasing occur months in advance.
• ▪State election officials warn that implementing the U.S. Postal Service rule so close to the November 2026 midterms will cause severe administrative delays and potential voter disenfranchisement.

Federal election data control

• ▪The coalition of challenging states argues that requiring them to identify mail-in voters to the U.S. Postal Service violates federal privacy protections governing records of First Amendment activity.
• ▪Nevada Deputy Secretary of State Mark Wlaschin warned that the U.S. Postal Service rule's provision to share voter data with law enforcement could suppress voter participation.
• ▪Voting rights groups and Democratic state officials argue that the U.S. Postal Service rule allows the federal government to exert unprecedented control over state-run elections and voter data.
