I don't think anyone is insinuating that Bush's signing of the CFR bill makes him a Democrat.
I'd have vetoed it, but that Bush didn't is not proof of his so called liberalism.
But it certainly wasn't a "conservative" thing to do, particularly when he admitted when he signed it that it was unconstitutional.
I like Bush as a person, but I'm increasingly disappointed with this sort of pragmatism. It really gets us no closer to bringing this nation back to its founding principles.
Barry Goldwater, OTOH, was never pragmatic, could NOT get elected, and turned lefty in his later years. Go figure. :-)
