By putting so much late into Iowa I think DT is making a big mistake. It is not the polls that will win Iowa, it is the organization getting out their voters. And in that Cruz has Trump far outstripped. He might bring out a brig crowd and trot Sarah, but he Ted has invested in a large local organization. I believe that Ted will let a little bit of the air out of Trump caucus night. Then, there’s no telling what kind of trash that DT will talk! Go TED!
Cruz and Cruz supporters are building up a set of expectations that Cruz will win Iowa. And if he doesn't - it is over.
