California elections, June 2012

The California state elections, June 2012 were held on June 5, 2012 and included two propositions, primary elections for each party's nominee for President, and primary elections to determine the top-two candidates for California's Class I seat to the United States Senate, all of California's seats to the House of Representatives, all of the seats of the State Assembly, and all odd-numbered seats of the State Senate, who will compete against each other in a run-off on November 6, 2012.

This was the first election with California's newly implemented nonpartisan blanket primary in effect, pursuant to Proposition 14, which passed with 53% voter approval in June 2010. Additionally, in November 2010, voters approved Proposition 20, which authorized a California Citizens Redistricting Commission to re-draw congressional district lines, in addition to its current job of drawing state senate district lines and state assembly district lines, taking away that job from the California state legislature. This was the first election which used the Citizens Redistricting Commission's maps.
