Deuel County is a typical eastern South Dakota county in its political history, which is somewhat akin to the Midwestern states of Iowa and Minnesota. It was strongly Republican in its early years, with no Democrat exceptWilliam Jennings Bryan gaining forty percent up to 1928. Franklin D. Roosevelt in 1932 became the first Democrat to carry the county, but lost it toAlf Landon in 1936, whilst – like most of the Midwest – the county showed a powerful anti-Roosevelt trend in 1940 and 1944 due to opposition toWorld War II. From 1964, the county showed a strong trend towards the Democratic Party – so much so that it was one of only 130 counties nationwide to support South Dakota nativeGeorge McGovern in 1972 againstRichard Nixon, and one of only five nationwide to have supported both landslide losers Landon and McGovern.[a]
Between 1976 and 2010, Deuel was a competitive swing county, voting for the winning candidate in every election until 2008 whenBarack Obama lost by 34 votes. Over the past three elections, however, Deuel – in common with many rural counties nationwide – has shown an abrupt swing towards the Republican Party.Donald Trump’s 2016 win was the largest sinceDwight D. Eisenhower in 1952.
