Analysis

South Dakota, a majority-White, mainly-rural state in the Midwestern Plains, is normally a Republican stronghold at both the state and presidential levels, despite being more populated than—and voting to the left of—neighboring North Dakota. It hasn't voted for a Democratic presidential candidate since Lyndon B. Johnson carried it in 1964, against the backdrop of his nationwide landslide victory. It has only been competitive (within 5 points of a Democratic victory) in three elections since then: 1976, 1992, and 1996, all elections the Democratic nominee won. Even South Dakota Senator George McGovern failed to carry his home state as Democratic nominee in the Republican landslide of 1972.

Despite Trump's win in the state, Biden flipped majority-Native American Ziebach County back to Democratic after it flipped red in 2016. Meanwhile, Trump held the majority-Native American counties of Bennett, Mellette and Jackson, and grew his support in Corson County, particularly in white-majority precincts while Biden held on to Native American support in other majority-minority precincts in the state. Per exit polls by the Associated Press, Trump won 63% of White Americans, a group composing 94% of the electorate.^[29] A sparsely populated state with a rural and conservative lifestyle, South Dakota has an agrarian populist streak^[30] to which Trump made direct appeals. He campaigned personally in the state, using Mount Rushmore as a backdrop to cast himself as waging battle against a "new far-left fascism".^[31]

While Biden did not win Minnehaha County, home to the state's largest city, Sioux Falls, that Barack Obama carried by less than one percent in 2008, he reduced Trump's 2016 14.6-percent winning margin in the county to 9.4 points, although Trump received a higher percentage of votes in the county than Mitt Romney did in 2012. Biden became the first Democrat to win the White House without carrying Roberts County since Woodrow Wilson in 1916, as well as the first to do so without carrying Day County since Franklin D. Roosevelt in 1944, and the first to do so without carrying Marshall County since John F. Kennedy in 1960.
