Berkeley is the state's most liberal large city, with Democrats outnumbering Republicans by more than ten to one, according to the latest voter registration figures from the California Secretary of State. Newport Beach is the most conservative large city. Torrance and Chino are the most balanced cities, with an almost even number of conservative and liberal voters.
