I'm not sure how much play this will get. But this poll tells you a lot about the candidacies of Donald Trump and Jeb Bush. A new PPP polls shows Trump, not surprisingly, at the head of the GOP pack. But when PPP created head to head match ups with the other contenders, Carson, Fiorina, Rubio and Walker all beat Trump and in most cases handily. Except Jeb. Trump beat Jeb. So Trump really isn't that strong. He's just got a committed following that holds the ground in a crowded field. Another way of putting it is that as big a plurality as Trump has, the bigger deal is the majority that is clearly against him.
Meanwhile, Jeb is weak and nobody likes him.
