California implemented an "all-party primary" system in 2010, funneling all candidates from every party onto a single ballot for the top two spots. Experts note that while this system has increased voter turnout, its impact on moderating political fields has been mixed and it means there is no genuinely safe district. Massachusetts voters will consider a similar change this fall when deciding Question 3.

California's top-two primary system, designed to encourage moderate candidates by requiring cross-spectrum appeal, often results in typical partisan general elections with one Democrat and one Republican. Critics argue the system fails to promote ideological diversity, as voters treat it like partisan primaries, and some races see strategic undermining of opponents. Proposals to repeal the system or adopt ranked choice voting are gaining traction.

California's top-two primary system, designed to promote moderation, often results in conventional Democratic vs. Republican general election matchups. Despite the system allowing two highest vote-getters to advance regardless of party, most races remain partisan due to California's roughly 60% Democratic vote share, which prevents two Democrats from advancing except in rare cases.
