I was one of the hardest-hitting conservatives on George W. Bush. Republicans didn't like me on George W. Bush. Republicans still don't like me on many things. If any Republican thinks I've been hard on Mitt Romney or Newt Gingrich or any of these guys, wait until Mitt Romney gets into office. I'll hold his feet to the fire just as much.
