As if anything in the history of the world could come as less of a shock, reality show star Sarah Palin quit her vaguely-defined bus tour that many suspected was a prelude to a serious presidential run.
Palin had set no clear itinerary for the bus tour; however, Real Clear Politics reports that her "One Nation" bus tour was to travel through the Midwest and the Southeast sometime this month. Instead, she has reportedly taken her family back to Alaska.
The former governor and possible GOP presidential hopeful has not explained her absence from the road, but we have 36 guesses why she may have opted to call it quits on the tour.
