Trump mail-voting order advances at U.S. Supreme Court

Last updated: Aug. 24, 2026

Canadians following the U.S. midterm elections are seeing a major fight over how millions of Americans may cast ballots by mail. The U.S. Supreme Court has opened a path for President Donald Trump's administration to pursue restrictions on mail voting, but it did not rule that the underlying executive order is legal. A separate nationwide injunction still blocks the U.S. Postal Service from carrying out key changes, while election deadlines are approaching rapidly.

What People Are Searching For

The central question is whether the Supreme Court has allowed Trump's new mail-voting restrictions to take effect for the November midterms. The answer is more limited: the court paused one lower-court ruling because it concluded the Democratic-led states challenging the order had sued too early. It expressly did not decide whether the president has constitutional authority to impose the measures.

Trump's March executive order calls for federal officials to compile lists of eligible U.S. citizens and directs the Postal Service to deliver mail ballots only to people appearing on qualifying lists. The Postal Service has also issued requirements affecting ballot envelopes and state voter-list submissions, according to AP's report on the postal rule.

What Is Confirmed

The Supreme Court's conservative majority lifted an injunction affecting 23 mainly Democratic-led states and Washington, D.C. The three liberal-leaning justices dissented. The majority stressed that its decision did not establish that government measures implementing the executive order would be lawful.

• The order was signed by Trump in March.
• Democratic officials in 23 states and the District of Columbia challenged it.
• About 30% of ballots in the 2024 presidential election were cast by mail, according to federal data cited by AP and The Globe and Mail.
• A 2025 Brookings Institution study cited by the sources found roughly four fraud cases per 10 million mail ballots.
• North Carolina is scheduled to begin sending ballots to military and overseas voters on Sept. 4.

What Is Unconfirmed

It is not yet confirmed how much of the administration's plan can actually be implemented before November. A separate nationwide ruling issued Aug. 11 by U.S. District Judge Indira Talwani still blocks the Postal Service from following the directives, according to NPR's account of the remaining injunction.

Further lawsuits are also expected. California Governor Gavin Newsom said his state plans another legal challenge, while New York Attorney General Letitia James said the states are exploring their legal options. The unresolved issue is therefore not simply whether the administration wants the rules in place, but whether courts will permit implementation before ballots start moving through the system.

The Bigger Picture

The dispute goes beyond one postal regulation. Democratic-led states argue that the Constitution assigns election-rule authority to states and Congress rather than the president. Republican-led states supporting the administration argue that states would still have input on final voter lists.

The timing intensifies the dispute. Election administrators are already preparing ballots, and the administration itself acknowledged in a July court filing that implementation would need to begin well before November. Once states begin mailing ballots, changing envelope formats, voter databases or postal procedures becomes substantially more difficult.

For Canadian readers, the immediate effect is indirect: the rules concern U.S. elections, not Canadian voting. The significance lies in the political and legal uncertainty surrounding the November contest for control of the U.S. Congress, a major event closely followed in Canada.

Latest Status

The Supreme Court has given the Trump administration an interim procedural victory, not a final ruling on presidential authority over mail voting. The nationwide injunction against USPS remains a major obstacle, and new court action could again stop or reshape the proposed rules. The next meaningful change will depend on whether lower courts revisit the new Postal Service rule and whether those decisions return to the Supreme Court before states begin sending ballots in September.

FAQ

Did the Supreme Court ban mail-in voting?

No. The court did not ban mail voting or rule that Trump's restrictions are constitutional. It paused one lower-court injunction on procedural grounds.

What does Trump's mail-voting order require?

The order directs federal agencies to develop citizenship or eligibility lists and calls for USPS to deliver mail ballots only under new list-based requirements. Postal rules also include changes involving ballot envelopes and voter-list submissions.

Are Trump's mail-ballot rules in effect now?

Not fully. A separate nationwide injunction issued by Judge Indira Talwani remains in place against USPS implementation, and further litigation is continuing.

When do U.S. midterm ballots start going out?

North Carolina is required to send ballots to military and overseas voters on Sept. 4. Other states follow soon afterward, leaving little time for nationwide procedural changes.

How common is mail voting in the United States?

About 30% of ballots in the 2024 presidential election were cast by mail, according to federal data cited in the supplied reports. That scale means even technical postal changes could affect a large number of voters and election administrators.

Why does this U.S. voting case matter to Canadians?

The ruling does not change Canadian election rules. Its relevance in Canada comes from the uncertainty it creates around the U.S. midterm elections, which will determine control of Congress.
