California is the most populous U.S. state and as a result has the most representation in the United States House of Representatives, with 53 Representatives. Each Representative represents one congressional district.
The 1990 census gave California seven additional congressional seats. Attempts by the legislature to draw up new districts were unsuccessful, as three different plans drawn up by the Democratic-controlled Legislature were vetoed by Republican governor Pete Wilson. In September 1991 the California Supreme Court took jurisdiction over the redistricting process to break the stalemate. Districts were drawn up by a panel of retired judges.
After the 2000 census, the California State Legislature was obliged to complete redistricting for House of Representatives districts (in accordance with Article 1, Section 4 of the United States Constitution) as well as California State Assembly and California State Senate districts. It was mutually decided by legislators that the status quo in terms of balance of power would be preserved - a so-called Incumbent Protection Plan. A bipartisan redistricting effort was done, and districts were configured in such a way that they were dominated by one or the other party, with few districts that could be considered competitive. In some cases this resulted in extremely convoluted boundary lines.
In the 2004 elections, a win by less than 55 percent of the vote was quite rare. This was seen in only five out of 80 State Assembly seats and two out of 20 State Senate seats up for election. The congressional seats were even less competitive than the state legislative districts - just three of the 53 districts were won with less than 60 percent of the vote in 2004.
Proposition 11, a California ballot proposition known as the Voters FIRST Act, was approved by the voters on November 4, 2008. It removed from the California Legislature the responsibility for drawing the state's congressional districts, and gave the responsibility instead to a 14-member Citizens Commission. The U.S. Supreme Court upheld the constitutionality of removing the responsibility from the legislature. The proposition also required that the districts drawn up (1) comply with the federal Voting Rights Act; (2) make districts contiguous; (3) respect, to the extent possible, the integrity of cities, counties, neighborhoods and "communities of interest"; and (4) to the extent possible, make districts compact. Several of these terms are not defined in law.
Governor Arnold Schwarzenegger had earlier proposed placing the redistricting process in the hands of retired judges, which was on the November ballot as an initiative in a special election (called by the Governor on June 14, 2005), Proposition 77. The special election was held on November 8, 2005. However, the initiative was overwhelmingly defeated, with 59 percent voting no. All initiatives, including those proposed by the Governor's allies and several independent initiatives, failed that year.
The California Citizens Redistricting Commission certified final district maps on August 15, 2011, and they took effect with the 2012 election. The new districts are described as more "purple" than "red" or "blue" - that is, more mixed in electoral composition compared to the mostly "safe" districts of the previous decade, where incumbents were almost guaranteed re-election. An interactive map comparing the old districts with the new ones is available via the Los Angeles Times.
These new districts, combined with demographic trends over several decades that favored the Democratic party, resulted in a gain of four House of Representatives seats for California Democrats in the 2012 elections.
