Nonpartisan Blanket Primary - Use in California

Use in California

California's blanket primary system was ruled unconstitutional in California Democratic Party v. Jones in 2000 because it forced political parties to associate with candidates they did not endorse. Then in 2004, Proposition 62, an initiative to bring the nonpartisan blanket primary to California, failed with only 46% of the vote. However, Proposition 14, a nearly identical piece of legislation, passed on the June 2010 ballot with 53.7% of the vote.

Under Proposition 14, statewide and congressional candidates in California, regardless of party preference, participate in the nonpartisan blanket primary, and the top two candidates advance to the general election. This does not affect the presidential primary, local offices, or non-partisan offices such as judges and the Superintendent of Public Instruction.
