You can easily see Jeb's campaign people sweating inside a small room trying to figure out a Trump strategy. They probably thought "we could attack him for being a crazy bat out of hell", but realized that people like that " straight talk" about him (or chose to overlook) even if it included things about Megyn Kelly's menstruation, McCain's war record, Latino comments etc. Then they figured "why not attack his extreme positions?" But realized that will not go well with the primary crowd. Now sweating more profusely, they settled on "let's attack his liberal views. We have clips from Larry King and everyone hates liberals." It was the only option they had in the face of an angry crowd. But the thing is all Trump needs to do, as he's been doing, is simply say he saw the error of his ways and all is forgiven because the caucus goers already believe that he's a straight shooter and it's refreshing for them.
Backfire written all over it. Wait till Trump brings out Jeb's record on immigration and common core. Hell, he doesn't even need to because it's not gonna come to that.
