Political people do and say things for political reasons. I like the people you mentioned, but they were obviously wrong. Sarah is quiet about Newt now, Mike Reagan has tried to give Newt advice, Herman Cain knows it is over but would never tell Newt to quit.
Just the way it is. When you know you can’t win, you choose the next best than yourself, if Newt thinks Romney is better than Rick, so be it. But Newt has no way to win, not even at a convention. A guy that won 2 Southern states and lost to Ron Paul in more than a few would never be nominated at a brokered convention.
