A second injunction barring the U.S. Postal Service from proceeding with its proposed changes for the 2026 elections remains in place, though the administration, citing the Supreme Court’s decision Monday, has urged the courts to quickly lift it.Racing against that clock, their opponents also swiftly returned to the courts to try and ensure Trump cannot enact the new restrictions.On Wednesday, a coalition of Democratic states at the forefront of the fight filed a new federal lawsuit against the Postal Service asking the court to block the changes, a move that will likely put them on a fast track back to the Supreme Court and leave election officials contending with messy legal rulings for some time to come.“Across the country, states are already deep into preparations for the 2026 elections,” New York Attorney General Letitia James said in announcing the lawsuit. “Now, at the last moment, the federal government is attempting to meddle in those preparations and potentially threaten countless Americans’ right to vote.” In a separate case, voting rights groups and Democratic leaders on Tuesday also asked federal courts to block the changes from going into effect for this November’s election.“The 2026 election has already begun, and this is sowing chaos,” said Paul Gronke, a political science professor at Reed College in Oregon and a founder of the Elections & Voting Information Center. Meanwhile, as the fight rages over how the U.S. Postal Service will handle mail ballots, North Carolina is preparing to send the first ones out next week. Jason Tyson, director of external affairs for the North Carolina State Board of Elections, said the state is still planning to send out its ballots as expected.“At this time, with so much left unresolved, we cannot comment on hypotheticals about what may or may not happen with the USPS and the executive order in the courts, as the situation is uncertain,” he said. “If it becomes necessary, we will do our best to comply with any court decisions.” Monday’s high court ruling added to a messy snarl of court cases over Trump’s March executive order that sought to allow the U.S. Postal Service to reject delivery of mail ballots to voters in states that don’t meet new federal requirements.The justices, who split along ideological lines, ruled only on a narrow legal argument and stressed their decision didn’t speak to the merits of Trump’s plan. While the case was pending, the Postal Service last week moved to finalize the new rules, action that a federal judge ruled Tuesday had violated a court order.The Postal Service rules require states to use a new online federal government system to send it a list of all voters that should receive mail ballots. The Postal Service would refuse to send ballots to anyone not on the list. The envelopes would have to meet new design standards, including unique barcodes that have to be checked by the Postal Service.Is it too late for changes?While the matter works its way through the courts, states across the nation have already designed, ordered, and paid for ballots that don’t necessarily comply with the new design guidelines (though North Carolina’s Tyson says theirs do).North Carolina’s ballots start going out Sept. 4. Seven other states, including New York, Wisconsin, and Minnesota, can start sending out their ballots the following week.Tammy Patrick, the chief program officer at the Election Center, a national nonprofit association for election administrators, said there was no way that states would be able to successfully shift to the new system if it were to be approved by the courts.“I don’t know of a single state where this could be adopted and rolled out quickly, and that I think is a real problem,” she said.Trump supporters who have been cheering his push to assert more control over elections hailed the court ruling but expressed concern that time was running out to set up the system for the November election.Catherine Engelbrecht, founder of the conservative, Texas-based anti-voter-fraud group True the Vote, said she supports the effort but acknowledged the Trump administration faces a daunting challenge in trying to set up the new system with fewer than 70 days to go before Election Day.“It’s a tall hill to climb, but somebody’s got to do it,” she said. Even if the courts block the Trump administration from moving ahead with the new plan for November, some voting rights advocates predicted that the president would still look for other ways to impose his policies.Jared Davidson, an election law attorney at Protect Democracy, said that the Trump administration continues to face legal setbacks in its efforts to impose federal regulations on elections because the Constitution gives states primary responsibility for running elections.“In the days and weeks ahead I think we can all expect that this administration will throw all kinds of spaghetti at the wall to see what sticks,” said Davidson. “But the law could not be clearer that this is an effort to take control over elections by an executive where there is no authority to do that whatsoever.”Dion Nissenbaum is Votebeat’s senior national reporter and is based in Houston.
