I disagree that Walker is 100% GOPe.
He has actually stepped forward and done things to solve some of the crises facing his state. His stand against public sector unions, for example, is entirely apart from the usual GOPe head-in-the-sand antics.
However, he does appear to hold several opinions I am less than satisfied with, starting with his stance on illegal immigration.
He is far from my favorite early-season candidate, but I personally have not yet decided if he would be an acceptable candidate - that is, I do not know enough to determine if he represents a different direction, or just a different pace toward the same liberal cliff.
