Are you saying you want Trump to act more like a politician?
He acted exactly like a politician, he had a set of talking point and that's what he went back to when he couldn't answer the question. When he really couldn't answer a question he acted indignant and repeated the talking points. That got a little tiring for me, because that's a tried and true trick politicians always revert to.
That he had very true specifics about what he would other that braggadocio about his awesome skills, didn't bother me too much at this point but I wasn't really that impressed with him overall.
