Unfortunatley for Sen. McCain, he will not be running under conditons as favorable to him as they were to Nixon in 1968 (HHH mini-comeback or no HHH mini-comeback).
I agree that McCain will not have the advantage that Nixon had. Namely, that the war was a Democratic war. This war is Bush's baby, and neither Democratic candidate will be compromised as HHH was in their opposition to it.
Nevertheless, I expect McCain to claim some sort of "plan" for ending the war. I doubt very much that he will run on the "Hundred Years War" platform. While it would be no more innovative than Nixon's "Vietnamizaton" (which Johnson was already implementing when Nixon took office), before the election, that will not necessarily be easy to prove.
I agree with the premise of the diary. I think the Democrat should just ignore whatever "plan" McCain says he is advocating, and just repeat over and over again that McCain says he wants a "Hundred Years War." Let McCain say he was in favor of such a war before he was against it. Let the Republican, for once, be in the position of trying to present a complex argument, while being met with a consistent chorus of "Na na ni na na, you said you wanted X, not you say don't want X, which is it, flip-flopper?"
