Before that, he didn’t have a web site with a platform on it, so he couldn’t “support” that platform. Frankly, I haven’t seen any indication that ANYTHING he’s said or done while running for President has shown any degree of wavering on his support for conservative principles.
I hardly see how that is risable. Huckabee in contrast makes statements every week where a few days later he has to correct, amend, or contradict them. McCain is more consistant, but his consistancy is about opposing conservative values.
