Federal election rules and congressional-map fight

Federal courts and the Supreme Court are weighing administration efforts involving USPS mail-ballot handling, voter-roll reviews, Executive Order 14399, and congressional redistricting. Missouri's attorney general has escalated a state congressional-map dispute to the Supreme Court ahead of a ballot-certification deadline, intensifying Elections Clause and federalism questions. Emergency litigation has allowed at least some implementation while ballot-access, data-protection, and election-timing issues remain unresolved; new coverage adds procedural detail but no decisive ruling.
