It is definitely true, of course, that talking about how the war is awful while you continue to give the Bush administration everything it wants is much, much worse than just uncritically supporting the war. The effect is precisely the same, but the latter at least could theoretically be idiocy undertaken in good faith while the former position wants to add some unjustified self-congratulatory moral preening on top of their de facto support of the war. Lugar deserves less than no credit.
