The United States Supreme Court has granted the Trump administration permission to move forward with parts of its initiative to revise mail-in voting regulations in preparation for the November 2026 midterm elections. In a 6-3 decision, the conservative majority of the court lifted an injunction that had previously halted President Donald Trump’s executive order. However, the administration’s plan faces ongoing legal challenges due to another injunction that remains in place, restricting the full implementation of the order.
Issued in March, the executive order mandates the federal government to compile a list of eligible voters based on citizenship, and stipulates that mail-in ballots should only be distributed to individuals on this list. It also proposes increased federal oversight of state and local election officials regarding voter eligibility. This order has been contested by Democratic officials from 23 states and Washington, DC, who argue that the Constitution delegates the responsibility of election administration to states and Congress. They caution that implementing significant changes close to the election could disrupt preparations and disenfranchise eligible voters.
A Massachusetts judge initially ruled against the order, stating that the president lacked the authority to dictate state administration of federal elections. This decision was upheld by an appeals court, and a subsequent nationwide injunction remains in effect. The Supreme Court’s decision to lift the first injunction does not guarantee the legality of all actions the administration might take to enforce the order. Consequently, the remaining legal battles are likely to influence the extent to which the policy can be enacted.
The court’s ruling has faced strong opposition from Democratic leaders and voting-rights groups who express concerns that the measures could lead to confusion and hinder eligible voters’ access to mail-in voting. In response, California and other states are preparing additional legal challenges. This legal dispute arises less than 100 days before the midterm elections, which will determine the control of the US House of Representatives and Senate. Mail-in voting continues to be a significant aspect of the US electoral process, with approximately 30% of ballots having been cast by mail during the 2024 presidential election.
Throughout his administration, President Trump has consistently questioned the security of mail-in voting and has advocated for broader reforms to election rules as part of his policy agenda. As the midterm elections approach, the outcome of these legal challenges will be closely watched, given the potential impact on how mail-in voting is conducted across the country.
