The region's distance from historical centers of power in the East, and the celebrated "frontier spirit" of its settlers offer two clichés for explaining the region's independent, heterogeneous politics. Historically, the West was the first region to see widespread women's suffrage, with women casting votes in Utah and Wyoming as early as 1870, five decades before the 19th Amendment was ratified by the nation. California birthed both the property rights and conservation movements, and spawned such phenomena as the Taxpayer Revolt and the Berkeley Free Speech Movement. It has also produced three presidents: Herbert Hoover, Richard Nixon, and Ronald Reagan.
