There's more over at his place. But I'd offer one theory. I think a sizable, maybe not a majority, of the conservative base doesn't actually believe in small government. They believe in government not not taking their tax dollars and using it to help people who they don't like. This goes back to state's rights, Jim Crow and reconstruction. I don't mean to impugn principled liberarians, but there's certainly a strain of "small government" conservativism that's rooted in those old racist notions.
... This is all a long way of saying that some conservatives don't hate big government, they simply want big government to work strictly for them.
