1) Obama is desperate
2) No teleprompter
3) If he acts angry, he will look like a loser, and turn off indies.
4) When Obama lies, Romney is well versed in FACTS.
Maybe Issa’s hearings can create such a distraction that Obama will be thinking of that instead of the debate at hand. Romney can further add to Obama’s misery by needling him into a thermonuclear meltdown. that would be must see tv.
The next debate is town hall, which could pose issues for Romney, but overall I think it is more negative for Obama. He prefers the podium and can’t get tough without appearing mean in this format.
