2025 in California

California Proposition 50, officially known as the Election Rigging Response Act, is an amendment to the constitution of the U.S. state of California, which was passed by voters in a special election ballot on November 4, 2025. At the urging of California governor Gavin Newsom, the proposition was put on the ballot by the Democratic-controlled California State Legislature. Approved by 64.4% of voters, the proposition's purpose was to redraw the state's congressional districts, replacing the ones drawn by the bipartisan California Citizens Redistricting Commission during the earlier 2020 redistricting cycle. The new districts will be used for the 2026 United States House of Representatives elections through the 2030 elections. Following the 2030 census, congressional redistricting authority will return to the independent commission under the normal decennial process.
