My initial, completely ignorant response is "Obama's a great liar and actor. It's scripted. He's deliberately lost the first one, draw close in the second one, and win in the third just in time for election night. It's just like a movie where the hero gets knocked down, but keeps on fighting, and finally wins at the very end."
I'll have to see if I maintain that attitude after I watch it.
