An effort to repeal California's "top two" primary system is underway. "The grassroots repeal effort is fueled by concerns that California's primaries are disenfranchising a majority of California voters by limiting choice to candidates from one party," read a news release from Steven Mavigilo, the official proponent of the proposed measure. Implemented in 2011, the primary system allows voters in statewide contests to choose any candidate from any party in the primary, regardless of their party registration. The top two vote-getters then advance to the general election, even if they belong to the same party.
