He is not down the line hard left on government spending and taxes. He isn't. He is crazy left on some social issues especially homosexual marriage but on many things that conservatives can support his position is still the same.
He's to the left of the overwhelming majority of Americans on partial-birth abortion. He supports a database of gun owners.
I don't give a rat's arse, considering these transtressions, that he may oppose a highway bill here or there.
