Haley Barbour was professional enough to see this and stepped aside this week. Sarah Palin should follow his lead. Ditto Donald Trump, Michele Bachmann, Mike Huckabee, Mitt Romney, Newt Gingrich and the any other of the same old cast of characters. Sadly, this probably includes former Florida Gov. Jeb Bush, as well as Ron and Rand Paul. OK. Mr. Wise Guy, you might inquire: Who’s left? So glad you asked!
