Until the beginning of the twentieth century, Fayette County was rock-ribbed Democratic. It was not won by a Republican until Theodore Roosevelt’s landslide win of 1904. The county voted after that for the winning candidate in every election until 1940, when opposition to Franklin D. Roosevelt’s economic and war policies gave the county to Wendell Willkie. Since then only two Democratic presidential candidates have gained an absolute majority in the county – the more recent of these two, Jimmy Carter in 1976, doing so by a single vote. Like all of the Upland South the county has seen a rapid swing to the Republicans in recent elections due to opposition to the Democratic Party’s liberal views on social issues: Hillary Clinton’s 2016 tally of 19.0 percent of the county’s vote is 15.7 percent worse than any Democrat before 2012.
