Looks like the pandering and backpedaling have begun. And he hasn't even announced yet.

The one criticism I have of Rand at this point, is he seems to be too coy in trying to be "adaptable" in some of his positions. More than once, I've heard him make some strange point in one venue and when questioned about it, he manages to turn the previous position into some more acceptable (to me) position. It will be interesting when he has to go on the record and see where his Constitutional disposition really lies.
