Everyone does NOT know where Newt stands...unless by that you mean “all over the place”.
Newt is openly for amnesty so we do know his plan. Bachmann is strongly against amnesty.
Perry needs to do better job in communicating, especially since this is crucial issue and his position unclear to many voters. Vague promises, like securing border are meaningless. I don’t live in IA or NH so I haven’t seen any ads.
