On November 21st, the Libertarian Party of California, the Peace and Freedom Party of California, and the Green Party of Alameda County joined a handful of voters and third party candidates for elected office to file a lawsuit alleging that California's top-two open primary system is unconstitutional. The suit argues that the top-two primary system disenfranchises minor parties as well as their voters and candidates for elected office by precluding them from participation in California's general elections.
