Trump’s Mail-In Voting Plan Blocked by the Supreme Court
By Drooid · · How we work
Core Event
On Monday night, September 14 2026, the United States Supreme Court issued an unsigned emergency order that left in place lower-court injunctions blocking the Postal Service’s new rule intended to enforce President Donald Trump’s March 31 2026 executive order on mail-in voting. Justices Samuel Alito and Clarence Thomas dissented; Justice Brett Kavanaugh filed a one-paragraph concurrence noting a “fair prospect” that the Postal Service possessed statutory authority but that implementation before the November 3 midterms would be “arbitrary and capricious.”
Background & Context
Trump’s order required states to submit voter-specific data to a USPS portal, use USPS-approved ballot envelopes with barcodes, and allowed the Postal Service to refuse delivery of non-compliant ballots. The administration argued the measures would prevent voter fraud, a claim repeatedly challenged by election experts. Twenty-three states and the District of Columbia sued, alleging the order violated the Constitution’s Elections Clause, which gives states authority over the “time, place and manner” of federal elections. A federal district judge in Boston issued a preliminary injunction, later reinforced by a second order, blocking the rule’s enforcement.

Data & Statistics
Official Statements & Responses
Civil-rights groups, including the NAACP, called the decision a “big win for voters.” State election officials from Utah, Oregon, Nevada and other early-mail states expressed relief that existing ballot-mailing processes could continue.
On-the-Ground Reports
Mail-in voting had already begun in several states. Alabama, North Carolina and Wisconsin were sending ballots as the Court’s decision was issued. A woman cast her primary mail ballot at the Belmar Library in Lakewood, Colorado, on June 29 2026, illustrating that the process was underway nationwide.
Conflicting Reports & Gaps
Sources differ on the exact vote split of the Supreme Court’s order. Fox News and several right-leaning outlets reported a 7-2 decision, while centrist and left-leaning outlets described it as 6-3. Both agree that Alito and Thomas dissented and Kavanaugh concurred. No source provides a final merits ruling, leaving the constitutional question of the Postal Service’s authority unresolved.
Verbatim Quotes
- “In my view, based on the briefing the Court has received at this interim stage, there is at least a fair prospect that the final rule falls within the Postal Service’s statutory authority,” — Brett Kavanaugh
- “It is alarming what the administration was seeking to do here,” — Kristen Clarke
What’s Next
Kavanaugh’s concurrence leaves open the possibility that the Postal Service could later implement a similar rule if the timing were less proximate to an election. The administration is expected to continue pursuing the underlying executive order in lower courts, while state and voting-rights groups prepare additional amicus briefs for future litigation.
