The U.S. Supreme Court has granted the Trump administration temporary permission to proceed with elements of its initiative to enforce stricter mail-in voting regulations ahead of the November 2026 midterm elections. In a 6-3 ruling, the court’s conservative majority lifted an injunction that had previously prevented President Donald Trump’s executive order from taking effect. Despite this decision, another injunction remains, meaning that the complete implementation of the order is still restricted by ongoing legal disputes.
Issued in March, Trump’s executive order mandates the federal government to compile a list of eligible voters based on citizenship and restrict mail-in ballots to individuals on that list. It also seeks to enhance federal oversight of state and local election officials concerning voter eligibility. Democratic officials from 23 states and Washington, D.C., have opposed the order, contending that the Constitution grants election administration authority to states and Congress. They also caution that significant alterations so close to the election could disrupt preparations and hinder eligible voters from participating.
A Massachusetts judge initially blocked the order, stating that the president lacked the authority to dictate how states manage federal elections. An appeals court supported this decision, and a subsequent nationwide injunction also remained in force. The Supreme Court emphasized that lifting the first injunction does not validate all actions taken by the administration to enforce the order, leaving room for ongoing legal challenges to shape the extent of its implementation.
Democratic leaders and voting-rights organizations have strongly criticized the ruling, arguing that the proposed measures may lead to confusion and complicate the voting process for eligible individuals. Meanwhile, California and other states are preparing additional legal challenges. This legal conflict arises less than 100 days before the critical midterm elections, where control of the U.S. House of Representatives and Senate will be decided. Mail-in voting continues to play a vital role in the American electoral process, with about 30% of the ballots cast by mail during the 2024 presidential election.
President Trump has consistently raised concerns about the security of mail-in voting and has advocated for broader revisions to election rules as part of his administration’s policy agenda. The ongoing legal battles and potential changes underscore the contentious nature of election administration in the lead-up to the midterms.
