President Trump cannot unilaterally end mail voting “everywhere” because the Constitution explicitly grants states—not the President—authority over how federal elections operate. While Trump signed an executive order on March 31, 2026, attempting to impose new requirements on mail voting through federal agencies, the legal power to actually allow or prohibit mail voting belongs entirely to state legislatures and election officials. This fundamental constitutional principle explains why his sweeping claim about ending mail voting nationwide faces immediate legal challenges and implementation obstacles that legal experts say make it “virtually impossible” to enforce. The distinction matters because it sits at the heart of how American elections work.
When Trump announced plans to end mail voting “everywhere,” he was operating from a position of limited authority. States like California, New York, and Michigan have already passed laws allowing mail voting, and only those states can change their own election rules. A presidential executive order cannot override state election law, which is why 23 states plus Washington, D.C., quickly filed lawsuits challenging the order. Understanding why election rules are state-based—not federal—is essential to understanding both what Trump’s order actually does and what it fundamentally cannot do.

What Trump’s Executive Order Actually Claims to Do
On March 31, 2026, trump signed an executive order titled “Ensuring Citizenship Verification and Integrity in Federal Elections” that attempts to establish new procedural requirements for mail voting. The order does not directly ban mail voting. Instead, it tries to impose administrative burdens by requiring states to notify the U.S. Postal Service 90 days before federal elections if they intend to allow absentee or mail-in voting, and to submit eligible voter lists to the USPS 60 days before elections.
The order essentially attempts to use federal agencies—specifically the USPS—as gatekeepers for state election processes. The distinction between what Trump claimed and what the order actually does is crucial. When headlines reported that Trump would “end mail voting everywhere,” the actual mechanism in the executive order is far more indirect. It’s essentially a notification requirement coupled with voter list submission requirements. The practical effect, according to states’ legal filings, would be to “dramatically restrict the ability of Americans to vote by mail” by creating new procedural obstacles. However, the order does not contain the explicit statutory authority to ban mail voting outright, which is why its legal status is uncertain and currently challenged in federal court.
The Constitutional Framework That Stops Federal Mail Voting Mandates
The U.S. Constitution, Article I, Section 4, explicitly states that states have the power to set the “times, places and manner” of federal elections. This language has been interpreted for over two centuries to mean that state legislatures—not Congress, not the President, and certainly not executive agencies—hold primary authority over how elections function. This is not a gray area of constitutional law; it is foundational to American federalism. When it comes to congressional elections, Congress has some ability to override state law, but the President has no such power whatsoever. This constitutional structure creates a hard limit on presidential authority.
A president cannot issue an executive order that overrides state election law. courts have consistently held that the President lacks the constitutional power to regulate federal elections unilaterally. When Trump issued a similar voting executive order approximately one year before this 2026 order, federal judges blocked it, ruling explicitly that he lacked constitutional authority. That precedent makes the legal outcome of the current order highly predictable, which is likely why legal experts like election law specialist Rick Hasen stated that “the timing here makes this virtually impossible to implement in time for November’s elections” and “it seems highly unlikely any of this could be implemented for 2026, even if it were not blocked by courts.”.
The 90-Day and 60-Day Requirements That States Now Face
The specific procedural requirements in Trump’s March 2026 executive order are worth examining because they reveal the mechanism by which the administration hopes to restrict mail voting. States must notify the USPS 90 days before federal elections if they intend to allow absentee or mail-in voting. Simultaneously, state officials must submit their eligible voter lists to the USPS 60 days before elections. For the 2026 midterm elections occurring in November, these deadlines were imminent when the order was signed in late March, leaving states with minimal compliance time.
The timing creates a practical problem that parallels the legal problem. Consider California, which conducts elections primarily by mail. The state would be required to notify federal USPS administrators 90 days in advance, submit voter rolls to a federal agency 60 days in advance, and coordinate with a federal postal service that has no statutory mandate to cooperate with these requirements. The burden falls on states to comply with a new federal requirement that the Constitution suggests the President never had authority to impose. For the 2026 election cycle specifically, states faced an impossible choice: attempt to comply with a constitutionally questionable order or face potential legal action from the federal government while fighting the order itself in court.
The Rapid Legal Response from States
Within days of Trump’s March 31 executive order, 23 states plus Washington, D.C., filed a coordinated lawsuit to block it. The states’ legal argument is straightforward: the order “dramatically restricts the ability of Americans to vote by mail, impinging on traditional state authority.” The lawsuit challenges both the constitutional basis of the order and its procedural requirements. States argue that the order violates Article I, Section 4 of the Constitution and potentially the Voting Rights Act and the Administrative Procedure Act.
The speed and coordination of this legal response reflects the seriousness with which states view the threat. This is not a partisan matter alone—the coalition includes states with Republican and Democratic leadership united on the principle that election administration belongs to states, not the federal government. The legal filing explicitly points to the President’s previous voting executive order, which was blocked by federal judges approximately one year earlier, as evidence that courts have already rejected similar attempts by Trump to override state election authority. The lawsuit filed in April 2026 essentially asks the court to reaffirm what it had already decided: the President lacks constitutional power to regulate elections.
Why Implementation Would Require Congressional Action, Not Executive Orders
Election law experts have emphasized a critical legal distinction that explains why Trump’s executive order has fundamental limitations. Only Congress—not the President—has constitutional authority to override state election laws when it comes to federal elections. Even Congress’s power is limited to setting rules for “times, places and manner” of congressional elections; presidential elections remain even more clearly within state control. This means that if the Trump administration genuinely wanted to end mail voting nationwide, it would need to convince Congress to pass legislation changing election law, something that would be politically difficult given that mail voting is supported by substantial majorities of American voters across party lines.
The executive order therefore functions as a symbolic gesture backed by procedural requirements, but it cannot achieve what Trump claimed it would achieve. Even if courts allowed the order to proceed, states could continue to allow mail voting. The order does not contain language that would strip states of their constitutional authority. What it does is create administrative friction—notification requirements, voter list submissions—that proponents believe will make mail voting more difficult to administer. However, these procedural hurdles remain subject to legal challenge, and the core question of whether the President can impose them at all remains contested.
State Mail Voting Laws Already in Place and Protected
Many states have already embedded mail voting into their election systems through state legislation. New Jersey, Nevada, Arizona, and Colorado conduct elections almost entirely by mail. These states passed laws through their legislatures that explicitly authorize and regulate mail voting for their voters. For Trump’s executive order to actually prevent mail voting in these states, either the states would need to repeal their own laws (which Democratic-controlled legislatures are unlikely to do) or Congress would need to pass federal legislation overriding them (which remains politically improbable). The current executive order cannot accomplish this directly.
California’s experience illustrates the complexity. California law allows mail voting and has since 1992. The state sent mail ballots to all registered voters during the 2020 general election without legal issue. If Trump’s order somehow forced California to stop allowing mail voting, the state would have to change its own election code—a step that would require legislative action and that state officials have already indicated they oppose. The legal dispute therefore is not about whether states can keep mail voting if they choose to; it is about whether the President can force them not to through executive action.
The Broader Question of Executive Power and State Authority
This conflict between Trump’s mail voting executive order and state election authority reflects a larger constitutional question about presidential power in the modern administrative state. Presidents increasingly attempt to regulate through executive orders and federal agency directives rather than by seeking congressional legislation. In areas where the Constitution clearly grants power to the states—like election administration—these executive attempts frequently run into legal obstacles. The fact that Trump’s similar voting order from approximately one year prior was blocked by federal judges suggests courts are unlikely to suddenly expand presidential power over elections.
The 2026 election cycle may be remembered less for whether Trump succeeded in ending mail voting and more for the constitutional pushback it generated. The legal principle that emerged—that states control their own election procedures and the President cannot unilaterally change them—reflects settled constitutional law. However, the repeated attempts to circumvent this principle through executive orders suggest that this legal question will return to courts repeatedly. For voters and election officials, the immediate practical effect is likely confusion and litigation rather than any actual change to how mail voting operates in states that have already authorized it.
Conclusion
Trump’s claim that he will end mail voting “everywhere” fundamentally misrepresents the constitutional authority he possesses as President. While his March 31, 2026, executive order creates new procedural requirements that could make mail voting administratively more difficult, it cannot and does not ban mail voting outright. The states retain constitutional authority over their own election procedures, and most states have already passed laws explicitly authorizing mail voting. The 23 states plus Washington, D.C., that filed suit against the order are not defending mail voting as a policy preference; they are defending the constitutional principle that states, not the President, control election administration.
For Americans concerned about mail voting’s future, the relevant question is not whether Trump’s executive order will succeed—legal experts expect it will be blocked by courts—but whether Congress might eventually pass legislation that could override state election laws. That would require a very different political process involving votes in the House and Senate, not unilateral action by the President. Until that happens, the constitutional framework established in Article I, Section 4 remains: states control the times, places, and manner of federal elections. No executive order changes that.
