The California Secretary of State has posted this unofficial list of candidates for the June 8, 2010 primary, for Congress and state office.
For the eight partisan statewide offices, each of the six ballot-qualified parties has someone running. The six ballot-qualified parties are Democratic, Republican, American Independent, Green, Libertarian, and Peace & Freedom.
For the 53 U.S. House races, Republicans are running someone in 52 districts, Democrats in 51, Libertarians in 21, American Independent in 7, Peace & Freedom in 7, and Green in 5. This is the largest number of AIP candidates for U.S. House in California since 1978, when there were eight.
All of the parties have contested primaries for Governor, except for the Libertarian Party. The Libertarian Party has a contested primary for the 59th Assembly district. Thanks to Ted Brown for the link.
