The Trump administration has asked the Supreme Court to allow new Postal Service rules concerning mail-in ballots to proceed ahead of the November midterm elections. This comes after U.S. District Judge Indira Talwani issued a temporary restraining order, blocking parts of the rule from taking effect. The Solicitor General, D. John Sauer, argued that the rule is necessary to prevent voter fraud and maintain confidence in the electoral process, describing it as a modest regulation of U.S. mail, not a federal takeover of elections.

Judge Talwani, however, stated that the rule is likely unconstitutional and practically impossible for states to comply with for the 2026 midterm elections, which are just over two months away. She highlighted that many states have already ordered ballots, some are legally required to send them out next week, and they lack the time and funds to redesign ballots, seek approval, update systems, train officials, and upload voter data to a new USPS portal. The rule requires states to get advance approval for mail ballot envelopes and return envelopes, create accounts for a new electronic portal, certify design approval, and upload each voter's information including name, address, and a unique intelligent mail barcode to the portal.

Despite the government's claim of combating voter fraud, Talwani found no evidence presented to support this concern. She emphasized that the USPS's interest in addressing an unsubstantiated problem through potentially unconstitutional means is outweighed by the significant risk of widespread disenfranchisement. The new rules could also lead to millions of ballots not being sent if they don't comply with uniform envelope styles or if voter lists aren't uploaded to the still-developing online portal. The Postal Service has said it will not determine voter eligibility or count ballots but requires states to provide lists of voters who received mailed ballots.

Election officials have expressed concerns about the feasibility of complying with thesedirectives, which would necessitate a complete overhaul of their operations. The administration filed its appeal just hours before North Carolina was scheduled to begin mailing out ballots, kicking off a wave of states shipping ballots for the upcoming elections. While the Postal Service initially indicated that the portal would be voluntarily available by next week and that envelope review wasn't currently mandated, the broader implications of the rule suggest significant logistical challenges and potential disruptions to mail-in voting processes.
