I didn't hear this before. Where did you read it? Hands down Newt is the Best Candidate for America. Obama would not have had a chance PLUS Newt would be the one to repeal and change the boy's errors.
I also don't believe it's because they think Ryan will cause the ticket to lose. It's because they don't want the ticket to win. They could be projecting or scheming, I don't know. But I know that a real conservative would value their principles so much that they would be enthusiastic about fighting for them in an election. They would not be so lacking in confidence that they think conservative values would make it impossible to win at the ballot box.
