9/11. bob beckel? >> i don't -- you know, i'll tell you, i consider myself somewhat of an expert on presidential politics but i do not understand that. as larry pointed out, george w. bush is popular again with republicans. i mean, you look at his numbers, favorable, unfavorable in iowa is quite high and the i were donald trump, i could think of a lot more people to attack than george bush and to keep it going from my standpoint makes absolutely no sense but again, nothing trump does makes any sense to me. maybe he knows something i don't know. >> larry, how does this help him? he has personal animosity for jeb bush but how does this help donald trump? >> i'm with bob. to me, it makes no great sense although it's his m.o. it's donald trump's m.o. to double down on anything he says that's really controversial
