I suppose it only makes sense for John Kerry to attack John McCain (unfairly, if you bother to understand the context) for suggesting that it was not terribly important when American troops exit Iraq, and I suppose it only makes sense that Kerry would make his attack so personal by suggesting that McCain is "confused" about basic facts of Middle Eastern history. These are low blows, of course, but understandable, given the way McCain turned on Kerry during the Swift Boat attacks of 2004. Oh, wait.
