Donald Trump just suffered a major defeat at the Supreme Court — and the timing could hardly be worse for the president.
With Americans already beginning to cast ballots in the 2026 midterm elections, the Supreme Court on Monday rejected the Trump administration’s emergency attempt to revive controversial new restrictions on mail-in voting.
And this wasn’t even close.
The apparent vote was 7–2.
Only conservative Justices Samuel Alito and Clarence Thomas publicly indicated that they would have granted the administration’s request.
The result means Trump’s new Postal Service rules will remain blocked while the legal battle continues — preventing the administration from putting them into effect for the upcoming midterms.
For millions of Americans who rely on mail voting, that could be enormously consequential.
Trump Wanted the Supreme Court to Step In
The dispute stems from Trump’s March executive order targeting mail-in voting and a subsequent U.S. Postal Service rule designed to implement parts of his plan.
Under the new requirements, states would have faced a series of major changes involving how mail ballots are prepared and processed.
States would have been required to provide information about eligible mail voters through a federal system and comply with new Postal Service standards for ballot envelopes, including unique identifying barcodes.
And there was a serious consequence for states that failed to comply:
The Postal Service could refuse to process noncompliant ballot mail.
That alarmed election officials and voting-rights groups, particularly because the changes were arriving just weeks before one of the most consequential midterm elections in years.
Some states have already begun sending ballots.
Judges Were Already Sounding the Alarm
The administration’s plan had already run into serious trouble in the lower courts.
U.S. District Judge Indira Talwani blocked the Postal Service rule, finding that challengers were likely to succeed in their argument that the agency lacked authority to impose key parts of it.
Then Trump received another setback.
U.S. District Judge Carl Nichols issued a separate injunction against the rule.
That detail is particularly notable:
Nichols was appointed to the federal bench by Donald Trump himself.
Nichols warned that implementing the requirements could increase the risk that otherwise valid absentee and mail ballots would not ultimately be counted.
With the clock rapidly running down before November, the Trump administration turned to the Supreme Court.
It wanted the justices to intervene and allow the Postal Service rule to take effect.
The Court has now given its answer.
7–2
The Supreme Court rejected the administration’s emergency request.
Alito and Thomas were the only justices who publicly indicated that they would have allowed the administration to move forward.
Justice Brett Kavanaugh — one of Trump’s own Supreme Court appointees — took a particularly interesting position.
Kavanaugh suggested there may ultimately be a legitimate legal argument that the Postal Service possesses authority to impose at least some of the requirements.
But he still agreed that the rule should remain blocked now because of something Trump could not change:
The election is simply too close.
Trying to dramatically alter voting procedures while ballots are already being distributed risks throwing an election into confusion.
And that is precisely what opponents of Trump’s plan had been warning about.
The Midterms Have Already Started
This isn’t a theoretical fight about some election years in the future.
Voting is already underway.
Mail ballots have begun going out in states including North Carolina, while other states are rapidly approaching their own deadlines.
Election officials argued that implementing an entirely new federal system at this stage could be extraordinarily difficult.
There were also questions about whether the federal infrastructure required to make the system work was even ready.
A whistleblower complaint raised additional concerns about the reliability of the government’s system for checking voter information, warning that technical problems could cause major disruptions.
The Trump administration, meanwhile, argued that its requirements were modest safeguards intended to protect election integrity.
But the lower courts weren’t convinced that imposing them at the last minute justified the risks.
Now the Supreme Court has refused to let the administration proceed.
This Is NOT the Final Word
There is one important distinction.
The Supreme Court did not issue a final ruling declaring Trump’s entire mail-voting policy unconstitutional or permanently illegal.
The underlying litigation continues.
That means Trump could ultimately prevail on some of the legal questions surrounding the Postal Service’s authority.
But politically and practically, Monday’s decision is still a major defeat.
Because whatever happens months from now, the administration wanted these rules operating for the 2026 midterms.
That isn’t happening under the current court orders.
States can continue using their existing procedures without being forced to comply with the new Postal Service requirements while the litigation proceeds.
A Remarkable Reversal
The decision is even more striking because the Supreme Court had given Trump a procedural victory in this same broader fight only weeks earlier.
In August, the conservative majority lifted an earlier injunction after concluding that the states challenging Trump’s executive order had gone to court too soon.
That ruling did not decide whether Trump’s policy itself was legal.
Once the administration issued its formal Postal Service rule, challengers returned to court.
This time, the legal landscape changed.
Lower courts blocked the actual regulation.
And when Trump returned to the Supreme Court asking for emergency help, seven justices declined to give it to him.
Trump’s Mail-Voting Fight Hits a Wall
Trump has spent years attacking mail-in voting, repeatedly claiming that widespread use of mailed ballots creates opportunities for fraud.
But extensive evidence has never supported his broader claims that mail voting produces widespread election fraud.
Nevertheless, Trump returned to office determined to use federal power to reshape the system.
The administration tried to give the Postal Service an unprecedented role in determining whether states’ ballot-mail systems met federal requirements.
Now that effort has hit perhaps its biggest obstacle yet.
Not from Democrats in Congress.
Not merely from a Democratic-appointed judge.
But from the United States Supreme Court — a court with a 6–3 conservative majority and three justices appointed by Trump himself.
And with the midterms rapidly approaching, the number Trump will probably like least is the simplest one:
7–2.
About the Author
Yes, for the moment this is a major positive decision. But, while a relief for now (since even Kavanaugh suggested he might revisit his position in the future if a similar case was brought before him in a timely manner) and we should cherish that relief (i.e., breathing spell), it likely means Trump will now double down on the use of ICE near the polls, potentially the military (after drumming up some chaos as a precursor to a “national emergency”), whatever other chaos he can muster up, and/or the “nuclear attack” as so decisively addressed in the article this past week from the well-respected, and conservative, former Judge Michael Luttig. In short, the battle to save our democracy from Trump and his noxious ilk ain’t over!
