The position he has now, doesn't appear to be his original position.  So what is to keep him from changing even further?  Are we to have a candidate who can move all over the place, but who is acceptable in his methods just because he allow dissent within his campaign and the people who follow him.  Wouldn't it be more effective to have a candidate who is consistant, yet still allows dissent?  That certainly would have more of an effect on people, than this way.
