The South Dakota Secretary of State has determined that Michael Myers will appear on the November 2014 ballot as an independent gubernatorial candidate. See this story.
From 1928 through 1994, there were no independent gubernatorial candidates in South Dakota, but independents did appear on the ballot for Governor in 1998 and 2002. Although the election returns for 1930, 1932, and 1934 list an “independent” candidate for Governor, in those three years, the candidate was actually the Communist Party nominee.
