Unfortunately, this kind of denunciation just feeds Moore's ego, and puts a feather in his cap for use amongst his Leftist sycophants: "I stood up to those GOP Convention Troglodytes and came out a winner!"
The way to beat Moore is to ridicule and marginalize him, not treat him as the serious threat to the Republic he feels himself to be. The GOP should have hired a comedian to dress up in a fat suit, stand next to McCain, and parody Moore's public statements - I guarantee Moore would have stormed out of the hall in a huff. ;)
Perfect marginalization of Moore.
