Overview

• California Republicans filed an emergency petition with the state Supreme Court to keep Proposition 50 off the Nov. 4 ballot, arguing violations of the single-subject rule, the constitution’s commission requirement and public-notice provisions.
• Proposition 50 would temporarily suspend California’s Citizens Redistricting Commission and implement a Democratic congressional map conditioned on Texas proceeding, with backers saying it could shift about five House seats.
• President Trump said he plans to sue California over the measure, while Newsom’s campaign dismissed the threat; election-law scholars cited in coverage said the new California challenge faces long odds.
• Texas Republicans advanced a mid-decade map projected to add roughly five GOP-leaning U.S. House seats, drawing immediate legal challenges including a lawsuit alleging racial discrimination under the Voting Rights Act.
• A Utah district judge ruled the legislature unlawfully undermined voter-approved redistricting reforms and ordered new congressional maps for 2026, with GOP leaders signaling appeals that could affect the timeline.
