Throughout the 20th century, Alpine County was a Republican stronghold in presidential and congressional elections. From 1892 until 2004, the only Democrat to carry Alpine County in a presidential election was Franklin Roosevelt in 1932 and 1936. In 1964, Alpine was one of only five counties in the state to back Barry Goldwater. It was among the five most Republican counties in the entire nation in 1892, 1908, 1920, and 1928. Warren Harding and Herbert Hoover gained over ninety percent of the county's vote. However, Alpine has become more of a Democratic-leaning county in recent elections. It was carried by John Kerry in 2004 and has stayed in the Democratic column since.
