My first reaction was "flop Sweat". On re-watching excerpts (you know, via Colbert & Stewart). It dawned on me that he looked, mostly, like an adolescent (God Bless 'em).
His emotive tones were those of someone trying out a public voice, listening to the sounds of his words as he said them.
And his deer-in-the-headlights manner is pretty much the same as a 17 year old in front of ANY audience.. not just the oft-referenced "frat boy" crowd. (and, note to media: not as familiar a refence to nearly as much of the audience as you think)
If he overcomes it, the footage will DEF be in his bio-reel.
