Last month, in front of a crowd of roughly 30 friends and supporters, Dr. Annette Bosworth announced her candidacy for US Senate at her family farm in Plankinton, South Dakota. Like many Republican Senate and House candidates, she is passionate about tax policy. "Never have a people been taxed as heavily as the American People and still called Free," Bosworth tweeted in July. Like so many Republicans, she has made the defunding and repeal of Obamacare her No. 1 issue. (She heads Meaningful Medicine, a private practice in Sioux Falls, South Dakota.) But unlike most Republican candidates out there, Bosworth is apparently a fan of Argentine Marxist revolutionary leader Che Guevara.
