Like most of Wyoming, Sublette County is overwhelmingly Republican. Since it was created in 1921, the solitary Democrat to carry the county was Franklin D. Roosevelt, who won a majority against Herbert Hoover in 1932 and a twenty-nine vote plurality against Alf Landon four years later. Since 1968 no Democrat has reached twenty-nine percent of Sublette County's ballots, and the only occasions a Republican has failed to pass seventy percent were when Ross Perot took substantial numbers of votes in 1992 and 1996.
