Politics in the San Francisco Bay Area is widely regarded as one of the most liberal in the country. According to the California Secretary of State, the Democratic Party holds a voter registration advantage in every congressional district, State Senate district, State Assembly district, State Board of Equalization district, County Board of Supervisors district, all nine counties, and all of the 101 incorporated municipalities in the Bay Area. The Republican Party holds a voter registration advantage in one congressional sub-district (the portion of the 9thinContra Costa County) and unincorporated Solano County.[1]
Since 1960, the nine-county Bay Area has voted for Republican presidential candidates only twice: in 1972 for Richard Nixon and in 1980 for Ronald Reagan, both Californians. The last county to vote for a Republican presidential candidate was Napa County in 1988 for George H. W. Bush.
All nine counties in the Bay Area currently have a voter registration advantage in favor of the Democratic Party.
