California’s Secretary of State only tallies the number of registered voters once in odd years. In 2013, the tally was as of February 10, and there won’t be another state tally until January 2014.
However, some California county election offices keep a running tally of the number of registered voters in each party. Los Angeles County, which holds 26% of the state population, is one of the counties that provides the data, updated daily.
As of July 7, 2013, the percentage of voters in Los Angeles County in each qualified party is: Democratic 50.95%, Republican 21.48%, American Independent 2.24%, Peace & Freedom .59%, Libertarian .53%, Green .51%, Americans Elect .05%. Independents are at 17.84% and voters registered in unqualified parties are at 5.80% (this category almost certainly includes people who left this part of the form blank).
As of February 10, 2013, the percentages in Los Angeles County were: Democratic 51.11%, Republican 21.55%, American Independent 2.24%, Peace & Freedom .51%, Libertarian .53%, Green .50%, Americans Elect .05%, independents 18.11%, members of unqualified parties and blanks 5.39%.
The numbers, as of July 7, are: Democratic 2,458,609; Republican 1,036,437; American Independent 108,031; Peace & Freedom 28,560; Libertarian 25,739; Green 24,521; Americans Elect 2,495; independent 860,723; miscellaneous and blank 280,092. The increase for Peace & Freedom during the last five months is probably because the party is working hard to increase its registration. In February it had 24,950 registrants in Los Angeles County.
