First sourced year

Shares are of the state’s total vote for president. Margin is the leader’s lead over the second-placed candidate. “Others named” lists every other candidate the figures give a line of their own.

Notes on the figures

  1. 1996 The source reports 32,478 votes under the label 'Independent' on one line with no candidate name, so the people they went to cannot be shown separately; they are counted in 'Other candidates'.
  2. 1936 The official table notes: Lemke's figure is marked with footnote 3: 'Independent Labor Party.'
  3. 1920 The official table prints no state total here; the total is the sum of the tickets it lists.
  4. 1920 The official table notes: Other tickets on the state page (in OthersState): Nonpartisan 34,707; Independent 900. The page does not name the Nonpartisan ticket's candidate.
  5. 1912 Roosevelt's Progressives held the Republican line in South Dakota; Taft was not on the ballot.
  6. 1896 The official table prints no state total here; the total is the sum of the tickets it lists.
  7. 1892 The official table prints no state total here; the total is the sum of the tickets it lists.
