Welch thinks we'll get to it eventually:

McCain will largely try to run out the clock, and hold onto the Palin bounce. But lest ye despair over the Shallowness of Our Politics or whatnot, remember this: There still is one very significant difference between the two candidates (meaning: not just energy policy, where both candidates will magically wean us off furriner-oil while creating X million "green jobs" by 2025) that McCain still wants to talk about, even if there, too, he has some constituents to not offend. That issue is Iraq, and the broader questions of the Middle East, the War on Terror, and foreign policy overall. We will yet get an election on substance before the gong strikes midnight.
