Politics
In its early history, Pitkin County favored the Democratic Party, for which it voted in every election between 1896 and 1916, one of the few Western counties to support Alton B. Parker in 1904. After that, it followed the trends of the nation until being narrowly carried by losing candidate Thomas E. Dewey in 1944. Pitkin subsequently remained Republican-leaning until the growing ski resort community drew its residents to the liberal George McGovern – rejected by a majority of the electorates of all but 129 other counties – in 1972. Since the 1980s, Pitkin has turned powerfully Democratic due to the threat of overdevelopment and the need for affordable housing and alternative mobility solutions. The last Republican to carry the county was Ronald Reagan in 1984, and George H. W. Bush in the following election is the last Republican to gain a third of the county’s vote. In this modern era, Pitkin has also frequently been one of the leading counties for leftist third-party candidates, being the fourth-best county for Eugene McCarthy in 1976, and the third-best for John B. Anderson in 1980.
