After a two-month break, Sarah Palin’s “One Nation” bus tour is back on: She’s heading to Iowa for the state fair, 30 miles south of Ames, where the famous straw poll takes place Thursday. Palin will not participate in the straw poll, and it’s not clear which day she is planning to go to Iowa. She will also visit Missouri and Indiana to visit the hometowns of Harry Truman and Ronald Reagan.
