The US Supreme Court has authorized the Trump administration to advance parts of its initiative to strengthen mail-in voting regulations ahead of the November 2026 midterm elections. In a 6-3 ruling, the court’s conservative majority lifted one of the injunctions that were obstructing President Donald Trump’s executive order. Despite this decision, another injunction remains active, leaving the full implementation of the order contingent upon ongoing legal disputes.
Issued in March, the executive order mandated the federal government to compile a list of eligible voters based on citizenship, restricting mail-in ballots to individuals on that list. It also demanded increased federal oversight of voter eligibility by state and local election officials. The order faced immediate opposition from Democratic officials in 23 states and Washington, DC, who argued that the Constitution assigns election administration authority to states and Congress. They further cautioned that significant changes so soon before the election could disrupt preparations and hinder eligible voters from participating.
A Massachusetts judge initially blocked the order, stating 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 place. The Supreme Court clarified that lifting the first injunction does not imply that all actions taken by the administration to enforce the order will be lawful, leaving room for remaining legal challenges to influence the policy’s future implementation.
The ruling has faced strong opposition from Democratic leaders and voting-rights advocates, who argue the measures may cause confusion and create obstacles for eligible voters. In response, California and other states are gearing up for further legal confrontations. This legal conflict is unfolding less than 100 days before the November midterm elections, which will decide the control of the US House of Representatives and Senate. Mail-in voting continues to be a vital component of the US electoral process, with approximately 30% of ballots being cast by mail during the 2024 presidential election.
President Trump has consistently raised concerns about the security of mail-in voting, advocating for more extensive changes to election procedures as part of his administration’s policy agenda. The outcome of the legal challenges surrounding the executive order will be pivotal in determining the extent of these changes as the midterm elections approach.
