Democratic Party Will Need Some Healing

Going by this heated exchange, looks like the DNC is going to need some major healing! Am I the only one here who thinks Obama is being pushed into the corner; he looks ready to blow up. I think this is a debate viewers will say exposed more of Obama's weaknesses. So far he has gotten testy when Clinton or Edwards attacks him, and even at times impatient. I am yet to see his trademark humor come up!
