Supreme Court blocks USPS ballot mail rule ahead of 2026 midterms

Key Points:

• Supreme Court declined to lift a lower court injunction blocking the USPS rule implementing Trump's ballot-mail regulations for the 2026 midterm elections, citing the government's unlikely success on the merits.
• Justice Brett Kavanaugh concurred with the majority but indicated a "fair prospect" that the USPS has statutory authority to enact the rule, leaving open the possibility it could take effect in future elections, such as 2028.
• The USPS rule mandates federal ballot-mail envelopes to include an election-mail logo, be scannable by high-speed equipment, and use unique barcodes, with states required to upload voter information to a Postal Service portal.
• Democratic state attorneys general sued, arguing the rule violates the Constitution's Elections Clause, while the Trump administration contends USPS is regulating mail rather than election procedures.
• Legal experts and dissenting justices suggest the rule might still be implemented in time for the 2028 election, with ongoing litigation expected, and note that Democratic states may face challenges opposing the rule without an imminent election.
