Vietnam

By all means, let this election be about Vietnam:

Bush obviously stands with the large contingent of Americans who are determined that, if we ever did face another Vietnam, never again would we pull out in a headlong rush and leave our allies sinking in the mud, clutching at our helicopter skids as we fly away, with the wreck of the new and better nation we had tried to build collapsing around their heads. Never again will we treat America's trustworthiness and honor, and the hopes of our friends, and the blood-sacrifices of our soldiers, like bad debts to be written off with a shudder.

Update (10/5): Cathy Young also thinks Vietnam is relevant.
