The U.S. Supreme Court has given a provisional green light to portions of the Trump administration’s initiative to tighten regulations on mail-in voting ahead of the November 2026 midterm elections. In a 6-3 ruling, the court’s conservative justices lifted an injunction that had been preventing President Donald Trump’s executive order from taking effect. Despite this development, another injunction remains active, meaning the full implementation of the order is still tangled in ongoing legal proceedings.
Issued in March, the executive order mandates the federal government to compile a list of eligible voters based on citizenship and restricts mail-in ballots to individuals on that list. It also seeks increased federal oversight of state and local election officials concerning voter eligibility. However, Democratic leaders from 23 states and Washington, D.C., have opposed the order, maintaining that the Constitution entrusts the authority over election administration to states and Congress. They have also expressed concerns that such significant changes close to the election could disrupt logistics and hinder eligible voters from participating.
A judge in Massachusetts initially ruled against the executive order, asserting that the president lacks the authority to dictate state administration of federal elections. This decision was later upheld by an appeals court, and a subsequent nationwide injunction was imposed. While the Supreme Court’s decision to lift the first injunction does not guarantee the legality of every administrative action to enforce the order, the remaining legal battles will likely define the extent of the policy’s eventual implementation.
The Supreme Court’s ruling has been met with sharp criticism from Democratic leaders and voting-rights organizations, who argue that the proposed measures could lead to confusion and obstruct eligible voters. States like California are gearing up for additional legal challenges. This controversy arises less than 100 days before the midterm elections, where control of the U.S. House of Representatives and Senate will be at stake. Mail-in voting remains a crucial component of the American electoral system, with around 30% of votes cast by mail in the 2024 presidential election.
President Trump has continuously questioned the security of mail-in voting and has advocated for comprehensive changes to election rules as part of his administration’s broader election policy agenda. As the legal wrangling continues, the outcome of these challenges could significantly shape the landscape of mail-in voting for the upcoming elections.
