South Dakota’s U.S. House-at-large race this year has three candidates on the ballot:  Independent B. Thomas Marking, Democrat Stephanie Herseth Sandlin, and Republican Kristi Noem.  On August 11, all three debated each other.  See this story.

South Dakota has a tradition of inclusive debates.  In 2006, all four candidates on the general election ballot for Governor debated each other, and all three candidates for U.S. House debated each other.  Similarly, in 2002, all three gubernatorial candidates debated each other.
