Does DeLay = GOP?

As we watch Tom DeLay and his supporters prepare an all-out counterattack against his critics, observers like Josh Marshall are wondering whether they're not making a big mistake:

When DeLay says 'bring it on' to his critics and marshals the full host of movement conservatism to defend him, I can't imagine that worries his critics a wink. I don't say that because these folks are impotent or can't raise a ruckus; they can. It is rather that in purely partisan terms the aim of the people leading the charge against DeLay is to raise his profile, to make him the face of the Republican majority on capitol hill -- with all his full measure of snarl, extremity and venality.
