From the founding of the state until 2008, the responsibility of redrawing the state's Congressional, Assembly, Senate, and Board of Equalization districts had been exercised by the California state legislature. In November 2008, California voters passed Proposition 11, the Voters FIRST Act, which took political redistricting responsibility away from the state legislature and instead established a 14-member statewide redistricting commissioncomposed of five Republicans, five Democrats, and four not affiliated with either of those two parties but registered with another party or as decline-to-state. The California Citizens Redistricting Commission was initially charged with updating the state assembly, senate, and Board of Equalization district boundaries starting with the 2010 census. Another initiative, Proposition 20, passed in 2010, expanded the Commission responsibilities to also include the state Congressional districts.
California is divided into 40 State Senate districts, each of which elects a senator to the State Senate. Twice the size of an Assembly district, each senate district contains about 931,000 people. The combined Senate roster is available from. The members of the California Senate Republican caucus are listed at. Prior to 1968, state senate districts were restricted such that one county could only hold at most one seat. This led to the situation of Los Angeles County, with 6 million residents as of 1968, receiving 600 times less representation than residents of Alpine County and Calaveras County, some of California's least populous counties. The Reynolds v. Sims decision by the United States Supreme Court compelled all states to draw up districts that were apportioned by population rather than geography. As such, boundaries were changed such that equal representation was provided.
California is divided into 80 State Assembly districts, each of which elects a member to the State Assembly. Each assembly district contains about 466,000 people. Each Assembly member is limited to three terms by a referendum passed by California voters. In March 2008, Proposition 93 unsuccessfully attempted to change term limits to a maximum of twelve years or six terms instead of three. The California Assembly Democratic Caucus members are listed at. The California Assembly Republican Caucus members are listed at.
