Analysis

South Dakota gave Republican nominee Donald Trump a more than 29-point margin of victory over Democratic rival Hillary Clinton, thus gaining him three electoral votes.^[16] The Mount Rushmore state's politics are driven by agrarian conservatism, with the eastern portion of the state being largely rural and considered an extension of the Corn Belt. The western portion of the state is even more conservative.^[17] South Dakota, like many neighboring majority-white Great Plains and prairie states in the Farm Belt, has not voted for a Democratic candidate since the landslide election of Lyndon B. Johnson in 1964.

Donald Trump carried most of the state's counties, including Hughes County where the capital city of Pierre is located, Pennington County which contains Rapid City, Minnehaha County which contains Sioux Falls, Brown County which contains Aberdeen, and Codington County which contains Watertown. Clinton won only five counties statewide: Todd, Buffalo, Dewey, and Oglala Lakota, all of which are majority Native American, and Clay County which contains the University of South Dakota.^[18] However, Trump did fare well with some Native American groups, and thus held the Native American-majority counties of Bennett, Corson, Mellette and Ziebach, along with the plurality-Native county of Jackson. Distinctly noticeable were the split of both the Pine Ridge and Standing Rock reservations votes and the majority-Native counties they contained: the western half of Pine Ridge (Oglala Lakota County) voted Democrat, while eastern Pine Ridge (Bennett and Jackson Counties) voted Republican, and while northern Standing Rock (Sioux County) remained heavily Democratic, southern Standing Rock (Corson County) swung Republican for the first time in three elections.
