Jon Karl: Trump ‘Unequivocally Helps’ Jeb Bush and Hillary Clinton

RADDATZ: "Will this hurt him? Is this different? Is this a turning point?"
KARL: "Well, this is what opened the floodgates of Republicans to finally come out and condemn Donald Trump. But look, he’s content to lead in the polls with 15-17 percent and I’ll tell you, Martha, there are two candidates that Trump unequivocally helps in this race, one now, the other in the future. The first is Jeb Bush because he becomes the vessel for all of the anti-Bush anger in the party and it’s in somebody who is clearly unelectable, will not get the nomination. And the second is Hillary Clinton. You heard him again, yesterday, say that he will not rule out running as a third-party candidate if that happens, it guarantees Hillary Clinton victory."
