 This is the first time that Joe Biden really has had an unscripted appearance before the country since that debate two weeks ago. He had a sit-down interview on national television last Friday. But this is going to be a much more raucous affair. It's going to be more chaotic. It is going to be the kind of thing that Joe Biden struggled with at that debate. So we'll see if he performs better tonight, although he has been in meetings at NATO and taking very long hours in the day the past couple days. So it will be a real test for him.
