Carson becomes the second Republican candidate to issue the threat that he'd leave the GOP if . . . http://www.cnn.com/2015/12/11/politics/ben-carson-donald-trump-leave-republican-party-threat/ This comes after the Washington Post reported that Republican Party officials discussed the possibility of deal-making to decide who will be the Republicans presidential candidate if no candidate secures enough delegates to win the nomination. It surprises me that Carson still does believe he stands a chance to get the nomination.
