And can you show me where this so called Populism is? He had an 88% ACU rating even being a 2 term blue state Senator.
Two terms and then he loses by 20 points in his home State. LOSER!
Also, I like that you noted his ACU ratings, but did you notice how his record tends to be a bit fluid during election years, when he seems to drift. His book, also was about as strong on economic conservatism as Huckabees ("It takes a family"). He's not a liberal, on social issues, he is absolute, but on economic issues, he tends to wander off, especially on spending.
Also, see the club for growth white paper.
