California Republicans sued in federal court to block Proposition 50, the newly approved U.S. House map that Democrats say could flip up to five seats next year. The NRCC-funded complaint argues mapmakers used race to create Latino-majority districts without evidence, violating the 14th and 15th Amendments, and seeks to halt the lines before 2026. Democrats cited Voting Rights Act districts; consultant Paul Mitchell declined comment. Newsom’s office said it expects the challenge to fail, posting "Good luck, losers." A ruling before Dec. 19, when candidate signature gathering begins, remains uncertain.
