Barack Obama Democratic Donald Trump Republican Measure 9 Amendment A Amendment E Amendment G The 2016 United States presidential election in South Dakota was held on November 8, 2016, as part of the 2016 United States presidential election 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 nominee, celebrity Donald Trump, and running mate Indiana Governor Mike Pence against Democratic nominee, former Secretary of State Hillary Clinton and her running mate, Virginia Senator Tim Kaine.

Chart of popular vote [15] South Dakota has only one congressional district because of its small population compared to other states.

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.

[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.
