And lord I hate to say it, but watching the pre-ordination proceedings at Invesco, they are indeed impressive. Chris Wallace just said it feels like history in the making. I'm not sure I would go that far, but it does feel like something biggger than (not to mention different from) a pedestrian presidential campaign. When you think about it, the situation's a little ironic. Being something more than a garden-variety presidential candidate has always been Obama's biggest strength. But appearing detached from the mudane and earthly concerns of we mere mortals has also become his greatest weakness. Tonight, the Obama campaign has selected a venue that emphasizes both the revolutionary nature of Obama 's quest as well as its grating grandiosity. Which theme ultimately defines the evening will determine whether the event is a success or a campaign-defining bust.
