Weekly Standard contributing editor and McCain adviser Robert Kagan writes in: "If recent success in the Iraq war is too closely associated with John McCain, will the anti-McCain conservatives now turn against the war itself? A trend in that direction does seem to be developing. Some of course turned against the war a long time ago, after having enthusiastically supported it. A handful were always against it. But now it seems that even those who strongly favored it last year, and also favored the surge, are beginning to question both its significance and, at a larger level, the significance of the war in Iraq. That is certainly the implication of those who suggest they can't see a difference between the Democratic candidates and McCain (and by natural extension Romney, as well) on the question of Iraq. And that is the direction of some of the latest attempts to downplay the importance of McCain's role in the Iraq war by suggesting that the war itself may not be all that significant in the broader war on terror. We've come a long way."
