California is a Democratic stronghold and considered to be one of the "Big Three" Democratic strongholds alongside New York and Illinois. Originally a swing state following statehood, California began regularly supporting Republicans by large margins for the first half of the 20th century, with Herbert Hoover calling the state home. This changed with the passing of Civil Rights laws by Democrats in the 1960s and the subsequent rightward shift of the Republican Party. Still, the party remained competitive with Democratic candidates until 1992. Richard Nixon and Ronald Reagan elected president carrying and residing in the state. This changed in 1992 amidst a struggling economy, when California flipped from Republican to elect Bill Clinton President. Republicans still won statewide contests in the state until the late 2000s, with Arnold Schwarzenegger elected governor as part of a recall effort.
