The Supreme Court made a major but preliminary ruling involving mail-in voting on August 24, 2026. The key point is that the Court did not rule that mail-in voting is unconstitutional or abolish it. Instead, it temporarily cleared the way for parts of President Donald Trump’s executive order restricting how mail ballots are administered to move forward.
What the Court actually did
The ruling was 6–3. The Court lifted a lower-court injunction that had blocked parts of Trump’s March executive order in 23 states and Washington, D.C.
The executive order involves several things:
- Federal citizenship information: The Department of Homeland Security can move forward with creating a federal list of citizens eligible to vote and sharing information with states.
- Mail-ballot rules: The Postal Service can proceed with developing certain new requirements concerning the design and handling of mail ballots.
- Enforcement: The Justice Department can prioritize potential prosecutions involving officials who knowingly issue ballots to people who are ineligible to receive them.
Here’s the really important part
The Supreme Court did NOT decide that Trump’s entire mail-voting order is legal.
The justices were dealing with whether the lower court had improperly blocked the administration while the litigation continues. The Court’s ruling therefore gives Trump an interim victory, rather than a final decision on the constitutionality of the executive order.
And there’s a significant complication: another federal injunction remains in place. That separate order currently prevents the Postal Service from implementing at least one of the most consequential provisions of Trump’s order nationwide.
So can you still vote by mail?
Yes. Nothing in yesterday’s Supreme Court ruling eliminated mail-in voting.
The immediate effect is more accurately described as:
The administration can proceed with portions of its plan while the underlying legal battle continues.
Whether the new requirements actually affect November’s midterm election will depend on additional litigation and what ultimately happens with the remaining injunction. Election officials are particularly concerned about the timing because states are already preparing and, in some cases, printing ballots and election materials.
Why this is potentially significant
The controversy isn’t really about whether Americans can simply choose to vote by mail. It’s about who has authority to establish the rules governing mail ballots.
States traditionally administer elections. Trump’s order attempts to impose significant federal requirements on the process. The states challenging the order argue that the president has exceeded his authority, while the administration argues that the federal government has authority over federal election-related matters.
The Supreme Court hasn’t resolved that underlying constitutional question yet.
So, in plain English:
Trump got a temporary green light, not a final victory. Mail-in voting remains legal. Some of his proposed restrictions can move forward, but another court order still blocks an important portion of them, and the legality of the overall plan remains unresolved.
If you’re interested specifically in what this could mean for Michigan voters in the November 2026 election, that’s a little different—and Michigan’s rules make the situation particularly worth looking at.
