California's top-two primary system, designed to foster moderation and competitive elections, has not significantly altered the partisan nature of statewide races. - The system allows the top two vote-getters to advance to the general election regardless of party.
- Statewide races often revert to partisan matchups due to a highly partisan primary electorate. - Same-party general elections are more common in local races in heavily Democratic areas.
- Studies show the system may encourage centrist appeals but is vulnerable to strategic gaming. Overall, while the top-two system has had some effects on candidate behavior, it has not fundamentally changed California's polarized political landscape.
