The Trump administration is pushing the Postal Service to require states to hand over voter registration lists in order to process mail-in ballots. Under the proposed rule, USPS would refuse to deliver ballots that don't match the submitted voter data, creating a pressure point on election administration. This could reduce mail-in voting in states that refuse to comply. The proposal is being challenged by Democrats and civil rights groups who argue it threatens election access, while the Washington Times frames it as a security measure during a time of declining USPS funding.
