This is entirely subjective, of course, and I was not its intended audience, but I think this event was a little like a balloon with a pinprick hole in it that began to deflate almost from the moment it began. The best moment was Obama summarizing Biden’s life story, and then it was followed by a half-hour speech by Biden that didn’t quite work and featured what ought to be worrisome signs for the Obama camp of Biden’s propensity for sliding off text in weird ways (as Daniel Halper notes above, he veered into a strange joke about his “drop-dead gorgeous” wife being a “doctor,” which is a “problem”).
