Redistricting

2025-2026

See also: Redistricting in California ahead of the 2026 elections

After Texas Republicans launched their congressional redistricting effort, California Gov. Gavin Newsom (D) tweeted on July 15, 2025, "two can play that game."[15] 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. 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. Gov. Gavin Newsom (D) signed the two bills and scheduled a Nov. 4, 2025, special election.[16] Voters approved the proposition by a 65%-35% vote, allowing the map that would make five districts more favorable to Democrats to take effect.[17]

2020-2021

See also: Redistricting in California after the 2020 census

After the 2020 census, 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.[18][19] 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. This map took effect for California's 2022 congressional elections.

How does redistricting in California work? In California, a non-politician commission draws both congressional and state legislative district lines. Established in 2008 by ballot initiative, the commission comprises 14 members: five Democrats, five Republicans, and four belonging to neither party. A panel of state auditors selects the pool of nominees from which the commissioners are appointed. This pool comprises 20 Democrats, 20 Republicans, and 20 belonging to neither party. The majority and minority leaders of both chambers of the state legislature may each remove two members from each of the aforementioned groups. The first eight commission members are selected at random from the remaining nominees. These first eight comprise three Democrats, three Republicans, and two belonging to neither party. The first eight commissioners appoint the remaining six, which must include two Democrats, two Republicans, and two belonging to neither party.[20]

Commissioners must meet the following requirements in order to serve:[20]

  1. Members must have voted in at least two of the last three statewide elections.
  2. Members cannot have switched party affiliation for at least five years.
  3. "Neither commissioners nor immediate family may have been, within 10 years of appointment, a candidate for federal or state office or member of a party central committee; an officer, employee, or paid consultant to a federal or state candidate or party; a registered lobbyist or paid legislative staff; or a donor of more than $2,000 to an elected candidate."
  4. Members cannot be "staff, consultants or contractors for state or federal government" while serving as commissioners. The same prohibition applies to the family of commission members.

In order to approve a redistricting plan, nine of the commission's 14 members must vote for it. These nine must include three Democrats, three Republicans, and three belonging to neither party. Maps drawn by the commission may be overturned by public referendum. In the event that a map is overturned by the public, the California Supreme Court must appoint a group to draw a new map.[20]

The California Constitution requires that districts be contiguous. Further, the state constitution mandates that "to the extent possible, [districts] must ... preserve the geographic integrity of cities, counties, neighborhoods and communities of interest." Districts must also "encourage compactness." State Senate and Assembly districts should be nested within each other where possible.[20]
