ST. LOUIS — Kitty Werthmann has made a career out of warning Americans that fascism is on its way. The 84-year-old native Austrian survived the Third Reich and, in her dotage as a leader of the South Dakota branch of the Eagle Forum, has recorded tapes and videos explaining just how Hitler took power. She made her case during George W. Bush’s presidency, but the audience was small–fringe conservative activists, radio hosts like Alex Jones. Then came President Obama. On Saturday, at the “How to Take Back America” conference here, Werthmann found herself speaking to an packed room of conservative activists about the parallels between the rise of Obama and the rise of Hitler.
