Trump's Mail-in Ballot Power Grab Exposes Why DOJ Has Been Demanding State Voter Data

The Federal Takeover Blueprint

President Donald Trump signed an executive order last week that finally explains why his Justice Department has been waging a months-long legal campaign to seize voter registration data from states across the country. The order directs the federal government to build a citizenship verification system that would compare state voter rolls against federal databases, then use that data to control who receives mail-in ballots.

The plan would require states to submit "verified" voter lists to federal agencies, direct the Department of Homeland Security to compile "State Citizenship Lists" of eligible voters, and order the U.S. Postal Service to deliver ballots only to people on approved federal lists. States that refuse to comply could lose federal funding.

Twenty-three Democratic states and the District of Columbia filed a lawsuit on Friday in federal court in Massachusetts to stop the order, arguing it violates the Constitution's allocation of election authority to states and Congress, not the president.

"The EO disregards States' inherent sovereignty and attempts to arrogate to the President the States' and Congress's constitutional power to regulate federal elections," the states wrote in their complaint, warning the directive tramples "bedrock principles of federalism and separation of powers."

The Data Grab Campaign

The Justice Department has filed 29 separate lawsuits against states that refused to voluntarily hand over their voter registration data. So far, 17 Republican-led states have complied with the administration's demands.

The order makes clear what the administration plans to do with that data: flag voter registrations by people the federal government suspects might be noncitizens, guide DOJ investigations and prosecutions, and impose a standardized mail-in voting system built around federally verified voter lists.

Trump has repeatedly attacked mail-in voting since his 2020 loss to Joe Biden, when approximately 66.4 million Americans voted by mail during the pandemic. "Cheating on mail-in voting is legendary," Trump said as he signed the order. "It's horrible what's going on. I think this will help a lot with elections."

A Constitutional Collision Course

Election law experts say the order is heading for a swift legal reckoning. The Constitution's elections clause gives Congress the authority to "make or alter" election rules for federal offices, but grants the president no direct control over how elections are administered.

Derek Muller, a law professor at the University of Notre Dame, told the Washington Examiner that the order raises both constitutional and practical concerns about how such a system could function.

"It's very complicated," Muller said, noting the order appears to contemplate multiple overlapping voter lists maintained by states, federal agencies, and the Postal Service. "There are just all these practical logistical concerns with election administration that are not conducive to this kind of layer of federal oversight."

U.S. elections are uniquely decentralized, conducted by election officials across thousands of state and local jurisdictions rather than by a single national system. The order would upend that structure by inserting federal control over who can vote by mail.

The Logistical Nightmare

The mechanics of Trump's proposed system remain unclear. The order appears to contemplate at least three separate databases: a federal citizenship list compiled by DHS, a state-generated list of voters eligible to receive mail ballots, and a Postal Service list of individuals authorized to receive and return ballots through the mail.

What the order does not explain is how those lists are supposed to connect or which list ultimately governs who can vote by mail.

Timing poses another major obstacle. The order suggests states would need to submit verified voter lists well ahead of elections, even though many states allow voter registration and absentee ballot requests close to, or even on, Election Day.

"There are real feasibility concerns in trying to make something like this happen," Muller said.

Uneven Enforcement Ahead

Even as lawsuits move forward, Muller said the path of enforcement could be uneven. Early injunctions in some states are likely, but it remains unclear how broadly those rulings would apply nationwide.

"I do think there is a degree of uncertainty about what might happen," Muller said, noting some states could face competing pressures between complying with the administration's order and adhering to their own election laws. That could lead to additional litigation or a patchwork system in which the order is enforced in some states but blocked in others.

The result could be chaos: eligible voters in some states receiving ballots while identical voters in neighboring states are blocked, all based on which federal judge issues an injunction first.

Muller suggested that certain elements of the plan, such as voluntary data-sharing between states and federal agencies to verify citizenship, could have practical value if implemented carefully as a back-end check. But the order goes far beyond voluntary cooperation, mandating federal control over state election systems and threatening funding cuts for noncompliance.

The lawsuit from 23 states, led by California, represents the opening salvo in what will likely be a protracted legal battle over whether a president can seize control of election administration from states. Given the clear constitutional limits on presidential power over elections, experts predict this will be one of the fastest Trump orders to face a nationwide injunction.

What remains to be seen is whether Republican-led states will continue complying with federal demands even as courts strike down the legal authority behind them.
