President Donald Trump's appointed postmaster general informed senators during testimony that the U.S. Postal Service would refuse to deliver mail-in ballots in states that do not provide their voter rolls to the administration, according to reports about the hearing.

The proposed policy shift represents a significant change to how USPS handles election-related mail and comes amid ongoing legal and political disputes over voting access and data sharing between state election officials and federal agencies.

What the Right Is Saying

Republican supporters of the administration argue that voter roll integrity is essential to election security. They contend that states have an obligation to share accurate voter data with federal authorities investigating potential fraud or irregularities.

The administration has maintained that ensuring the accuracy of voter rolls protects against duplicate voting and addresses concerns raised during previous elections about ballot integrity in certain jurisdictions. Supporters note that mail-in ballots already face verification procedures before counting.

Conservative legal scholars argue the executive branch has broad authority over federal agencies like USPS and that conditions on election-related services fall within presidential discretion over agency operations.

What the Left Is Saying

Democratic lawmakers and voting rights advocates argue that linking voter roll information to ballot delivery creates an unconstitutional barrier to casting ballots. Senator Amy Klobuchar of Minnesota, a senior member of the Senate Judiciary Committee, has previously argued that any conditions on mail-in ballot delivery could disenfranchise eligible voters.

Organizations including the Brennan Center for Justice have documented that voter roll maintenance is primarily a state function governed by each state's laws and constitutional provisions. Advocates contend that federal interference with ballot delivery based on data-sharing disputes violates the Voting Rights Act and the Constitution's Elections Clause.

Civil liberties groups warn that conditioning postal service on administrative compliance could prevent valid voters from having their ballots counted, particularly in states with no-excuse absentee voting laws already on the books.

What the Numbers Show

The Postal Service processed approximately 121 million pieces of election mail during the 2024 general election, according to USPS data. Of those, roughly 52 million were ballots mailed to voters from election offices.

Twenty-seven states and the District of Columbia currently allow no-excuse absentee voting by mail, meaning any voter can request a ballot without stating a reason. An additional nineteen states permit mail voting with specific excuses required.

Voter roll accuracy studies have produced varying estimates. The Pew Charitable Trusts found in 2012 research that approximately 24 million voter registrations in the United States were either inaccurate or no longer valid. However, more recent analyses by academic researchers have questioned some methodologies used in those calculations.

The Government Accountability Office has not published specific reports on USPS ballot delivery policies related to voter roll data sharing since this proposed rule is new.

The Bottom Line

The proposed policy faces likely legal challenges from voting rights organizations and states that may refuse to share voter rolls on constitutional grounds. Courts have historically been skeptical of conditions placed on fundamental voting rights, though the specific legal questions here remain untested.

States could respond by relying more heavily on in-person voting options or by accelerating ballot delivery through private carriers rather than USPS. Congressional Democrats may attempt to limit funding for implementation through appropriations riders in upcoming spending bills.

What to watch: Whether any states publicly announce they will withhold voter roll data from the administration, and whether postal workers unions or management raise concerns about being put in the position of determining which ballots get delivered based on administrative compliance criteria.
