Redistricting in California ahead of the 2026 elections
Redistricting is the process of enacting new district boundaries for elected offices, particularly for offices in the U.S. House of Representatives and state legislatures. This article covers redistricting activity in California after the 2024 elections and before the 2026 elections.
California's 52 United States representatives and 120 state legislators are all elected from political divisions called districts. District lines are redrawn every 10 years following completion of the United States census. Federal law stipulates that districts must have nearly equal populations and must not discriminate on the basis of race or ethnicity.
Congressional districts
Map drafting in California ahead of the 2026 elections has concluded.
Voters approved California Proposition 50 on November 4, 2025, authorizing the state to use a new congressional map from Assembly Bill 604 (AB 604) for the 2026 elections.[1] After Texas Republicans launched their mid-decade congressional redistricting effort, California Gov. Gavin Newsom (D) posted on X on July 15, 2025, "two can play that game."[2] On August 21, 2025, the California Legislature passed a redistricting plan setting a special election for a constitutional amendment to redraw the state's congressional district boundaries through 2030.[3] Heading into the redistricting effort, Democrats represented 43 of California's 52 Congressional districts, and Republicans represented nine.

Enacted congressional district maps
After Texas Republicans launched their congressional redistricting effort, California Gov. Gavin Newsom (D) tweeted on July 15, 2025, "two can play that game."[2] In August 2025, California began taking official action toward congressional redistricting ahead of the 2026 elections. Redistricting in California required the passage of a constitutional amendment in a November special election to permit the adoption of a replacement map through 2030. Voters approved the proposition by a 65%-35% vote, allowing the map that would make five districts more favorable to Democrats to take effect.[1]
The California Citizens Redistricting Commission voted 14-0 in favor of a new congressional district map on December 20, 2021, and delivered those maps to the secretary of state on December 27, 2021.[4][5] California was apportioned 52 seats in the U.S. House of Representatives after the 2020 census, a net loss of one seat compared to apportionment after the 2010 census.
