2020 United States presidential election in South Dakota

The 2020 United States presidential election in South Dakota was held on Tuesday, November 3, 2020, as part of the 2020 United States elections in which all 50 states plus the District of Columbia participated. South Dakota voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. South Dakota has three electoral votes in the Electoral College.
Trump carried South Dakota by 61.8%–35.6%, or a margin of 26.2%. Biden performed four points better than Hillary Clinton in 2016. Prior to the election, all 12 news organizations considered this a state Trump would win, or a safe red state. Despite this not being her home state, this was Jo Jorgensen’s best state with 2.65% of the vote.
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--its Northern counterpart. It hasn't been won by a Democrat since LBJ carried it in 1964, and has only been so much as competitive in four elections since then: 1976, Bill Clinton's 1992 and 1996 victories, and 2008. 
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, while he actually grew his support in Corson County, which is completely encompassed by the Standing Rock Indian Reservation, marking his increased percentage among Native voters. Per exit polls by the Associated Press, Trump carried Caucasians with 63%; they comprised 94% of the electorate. A sparsely populated state with a rural and conservative lifestyle, South Dakota has an agrarian populist streak 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".
While Biden didn't win Minnehaha County, home to the state's largest city, Sioux Falls, that Barack Obama won by less than one percent in 2008, he reduced Trump's 2016 14.6 percent winning margin in the county to 9.4, although Trump received a higher percentage of votes in the county than Mitt Romney did in 2012.
