USPS Says It Can Decide Whose Mail Ballot Counts. 25 States Just Sued to Stop It.
A new federal rule could get your mail ballot rejected before anyone even looks at your vote, and half the country's attorneys general are fighting back before the midterms.
Your mail carrier's job is to deliver your mail. Not to decide whether you're allowed to receive it.
That's the line at the center of a new lawsuit filed this week by 25 Democratic-led states against the U.S. Postal Service. It's over a rule that would let USPS reject mail ballots that don't match a federal list or that arrive in envelopes the government hasn't pre-approved, even when a voter's own state has already confirmed they're eligible and their ballot is legitimate.
That might sound like a paperwork fight between lawyers and a federal agency. It's not. It's about whether your ballot gets thrown out over a filing technicality, weeks before you'd ever find out.
FIRST: WHO ACTUALLY DECIDES WHO'S ALLOWED TO VOTE BY MAIL?
For as long as mail voting has existed, that call has belonged to state and local election officials. They're the ones who check your registration, verify your identity, and approve your ballot. The Postal Service's role has always been simple: pick up the ballot, deliver it, on time.
This new rule changes that. It asks USPS to check every mail ballot against a federal voter list, and reject any ballot that isn't on it, or whose envelope wasn't pre-approved by the federal government, regardless of what the voter's own state already decided.
WHAT HAPPENED
In March 2026, President Trump signed an executive order restricting mail-in voting. It directed USPS to collect voter eligibility lists from every state, require ballots to carry specific tracking barcodes, and deliver ballots only to voters who appear on a Department of Homeland Security citizenship list. It also required states to get their ballot envelope designs pre-approved by the federal government.
In June, a federal judge blocked the order's key provisions with a nationwide injunction, finding it likely unlawful. That held until August 24, when the Supreme Court temporarily paused the injunction as it applies to 23 Democratic-led states and Washington, D.C., letting the administration move toward implementation while the underlying legal fight continues. The Court was careful to say this wasn't a final ruling on whether the order is constitutional, only that implementation could proceed for now.
Two days later, on August 26, a coalition of 25 states, led by New York Attorney General Letitia James, filed a new lawsuit against USPS directly, seeking to block the rule before it can affect the midterms. "The USPS has no authority to decide who can and cannot vote by mail," James said. "This new policy will just create confusion and unnecessary costs." A separate suit from six additional states raises similar claims.
The clock is tight. States would need to compile voter lists, redesign ballot envelopes, get federal sign-off, and build new systems to transmit data to USPS, all within weeks of Election Day. USPS delivered nearly 100 million ballots in 2024, when roughly 30 percent of American voters cast their ballot by mail.
WHAT SUPPORTERS OF THE RULE SAY
The administration and the rule's backers frame this as an election security measure. Their argument: verifying that mail ballots go only to eligible, verified citizens protects the integrity of the count, and tools like tracking barcodes and a federal eligibility check add a layer of fraud prevention that today's system lacks. In their view, requiring standardized, pre-approved processes nationwide closes gaps that vary state to state.
WHAT THE LAWSUITS SAY
The states suing argue the Constitution gives states, not the Postal Service, the authority to run elections and decide voter eligibility. USPS is a mail carrier, they say, not an elections agency, and it has neither the expertise nor the legal standing to reject a ballot that a state already certified as valid. They also argue the timeline itself is the harm: building new list-matching and pre-approval systems in a matter of weeks, right before a major election, all but guarantees mismatches, delays, and eligible voters' ballots getting bounced for reasons that have nothing to do with whether they're actually allowed to vote.
WHAT WE DON'T KNOW YET
It's not yet clear how quickly a court will rule on this new lawsuit, or whether judges will pause the rule again while the case proceeds. The administration is also separately appealing the original nationwide injunction, so there are multiple legal tracks moving at once. We don't know how accurate the DHS citizenship list actually is, how many eligible voters might get flagged in error, or whether USPS can realistically stand up new verification systems before ballots start going out this fall. Watch for court filings and rulings in the coming weeks, they'll likely determine which rules are actually in effect by the time you request your ballot.
WHAT THIS MEANS FOR MARYLAND
Maryland is one of the 25 states in this lawsuit. Attorney General Anthony Brown joined the coalition, arguing the rule oversteps federal authority and would disrupt Maryland's own vote-by-mail process right as ballots go out for the midterms. That matters here on the Shore too: mail voting is how a lot of Queen Anne's County residents, including seniors, rural voters, and anyone who can't easily get to a polling place, cast their ballot. A federal rule that adds new list-matching and envelope pre-approval steps on a tight timeline could mean local ballots get flagged or delayed for reasons that have nothing to do with whether the voter is legitimate.
WHAT YOU CAN DO
- Check your voter registration and mail ballot status now through your state's official election website, before any new list requirements could cause a mismatch.
- If you plan to vote by mail, request your ballot as early as your state allows, and use your state's ballot tracker (most states have one) instead of waiting until the deadline to find out if there's a problem.
- Contact your state Attorney General's office or local election board to ask directly how this rule affects your state's process, and share this Dispatch so your community isn't caught off guard.
