US Postal Service mail-in ballot tracking rules face legal challenges and whistleblower claims

A federal judge temporarily paused new tracking rules as a whistleblower warns software flaws could reject valid ballots ahead of the midterms.

The short version

  • The Trump administration directed the US Postal Service to implement barcode scanning and tracking rules for mail-in ballots based on state-provided voter lists.
  • A Massachusetts federal judge placed a 14-day hold on the rules on August 27 following a lawsuit from 24 states and voting rights groups.
  • A whistleblower complaint publicized by Senator Richard Blumenthal claims the hastily developed USPS software risks rejecting entire ballot batches due to unverified barcodes.
  • The ongoing legal dispute and technical concerns come as early voting begins in September ahead of the November 3 midterm elections.
