Democrats appeal ruling leaving Trump mail-vote order in place

Americans first voted by mail in significant numbers during the Civil War. The Lincoln administration authorized Union soldiers to cast absentee ballots starting in 1864, when roughly 150,000 troops voted from the field — mostly for Lincoln. That wartime accommodation established the legal precedent that ballots can be cast without in-person polling-place appearance. Congress codified the modern framework for military and overseas mail voting with the Uniformed and Overseas Citizens Absentee Voting Act of 1986, which guarantees mail ballot access to all U.S. citizens serving in the armed forces or living abroad.

Mail voting expanded dramatically in 2020. The COVID-19 pandemic drove roughly 46% of all votes to be cast by mail in the 2020 presidential election — up from about 24% in 2016. States that had never offered no-excuse absentee voting scrambled to implement it. By 2022, mail voting had settled to approximately 29% of ballots cast — nearly one in three voters, making it a routine part of American democracy rather than an emergency accommodation.

President Trump signed an executive orderExecutive OrderA written directive from the President directing federal agencies to implement or change policy without requiring congressional approval.Key ConceptExecutive OrderA written directive from the President directing federal agencies to implement or change policy without requiring congressional approval.Open conceptBookmark on March 31, 2026 titled "Ensuring Citizenship Verification and Integrity in Federal Elections." The order directed USPS to deliver mail ballots only to voters whose names appear on state-submitted eligibility lists verified against DHS citizenship databases. It also required DHS to compile a list of confirmed U.S. citizens in each state and transmit that list to state chief election officials.

The USPS released a proposed rule implementing the order on May 29, 2026, one day after the district court's ruling. The proposed rule would require states to submit voter names, addresses, and unique barcodes tied to each voter's outbound and return ballot envelopes. The rule applies to general, special, and runoff federal elections — but not primaries or ballots sent to military and overseas voters.

U.S. District Judge Carl Nichols issued his ruling on May 28, 2026, refusing to grant Democrats a preliminary injunctionPreliminary InjunctionA court order that temporarily blocks a government action or policy while a lawsuit challenging it works through the courts.Key ConceptPreliminary InjunctionA court order that temporarily blocks a government action or policy while a lawsuit challenging it works through the courts.Open conceptBookmark blocking the executive order.

USPS hadn't yet taken enforcement action against any ballot mailing, and DHS hadn't finalized the citizen list — meaning Democrats couldn't show they had suffered a concrete injury that warranted emergency court intervention.

Nichols explicitly left the door open for future challenges, writing that plaintiffs may renew their motions if and when agencies take further implementing actions. He did not rule on the merits of whether the executive order was constitutional.

The Democratic National Committee, DSCC, DCCC, Democratic Governors Association, Senate Minority Leader Chuck Schumer, and House Minority Leader Hakeem Jeffries filed the notice of appeal on June 1, 2026. They chose not to wait for federal agencies to finish implementing the order before challenging it again. The appeal goes to the U.S. Court of Appeals for the D.C. Circuit, which will consider whether Nichols was right to find the case unripe.

The constitutional argument turns on Article I, Section 4 — the Elections ClauseElections ClauseConstitutional provision giving states and Congress power over federal electionsKey ConceptElections ClauseConstitutional provision giving states and Congress power over federal electionsOpen conceptBookmark — which states that states set the "Times, Places and Manner" of federal elections, subject to Congress's authority to alter those rules by statute. The president has no independent constitutional role in election administration. An executive order cannot substitute for a congressional statute.

The Brennan Center for Justice concluded in its analysis of the March 31 order that the federal government's citizenship databases are incomplete and sometimes inaccurate — meaning eligible American citizens could be dropped from DHS-compiled lists and blocked from receiving mail ballots.

Trump issued a first executive order on elections in March 2025 that attempted to impose proof-of-citizenship requirements on federal voter registration forms. Federal courts permanently blocked key provisions of that order, finding the president lacked constitutional authority to rewrite election rules that belong to Congress and the states. The March 2026 order targeting mail ballots is the second such executive action on elections, using the same constitutional theory that courts already rejected.

As of June 2026, five separate lawsuits challenge the March 31 mail-ballot executive order, filed by the DNC coalition, the League of Women Voters, the ACLU on behalf of voting rightsVoting RightsConstitutional and statutory protections guaranteeing citizens the right to register and vote without undue government barriers.Key ConceptVoting RightsConstitutional and statutory protections guaranteeing citizens the right to register and vote without undue government barriers.Open conceptBookmark groups in Massachusetts, LULAC, and a coalition of nearly two dozen states plus Washington, D.C. The parallel case in federal court in Boston remains pending before a separate judge.

The roughly 40.2 million eligible voters with disabilities in the United States — counted by Rutgers School of Management and Labor Relations — use mail ballots at higher rates than non-disabled voters. Rural counties face compounding challenges: the USPS proposed rule would require election officials in every county to match voter names and addresses with unique barcodes and transmit that data to USPS before any ballot can be mailed — a new administrative burden that smaller jurisdictions with limited staff may struggle to meet on midterm timelines. UOCAVA voters — military personnel and overseas citizens — are explicitly carved out of the proposed rule, creating a two-tiered federal mail-ballot system operating under different rules.

The D.C. Circuit now must decide whether the Democrats' challenge is ripe enough to hear on its merits, or whether to send the case back to Judge Nichols with instructions to wait for agency implementation. If the appellate court finds the challenge ripe, it could issue an emergency injunction blocking the order from taking effect before the November 2026 midterms — the first major federal election that the executive order would directly affect.

The USPS proposed rule published May 29 may itself change the ripeness calculation: now that USPS has taken a concrete implementing step, the ripeness objection that protected the executive order at the district level is weaker.

If the D.C. Circuit allows the executive order to stand, or if SCOTUS ultimately upholds it, the ruling would establish that a president can use an executive order to restructure how mail ballots are delivered in federal elections — without Congress passing a law or states changing their own election codes. That would shift power away from states and Congress toward the executive branch over the machinery of American elections.
