Fallout from this is not certain. I think he was right to apologize. But it could be the kind of thing that people get turned off by and rally around the President.
I think his prompt apology for being uncivil will take care of that. The RATS will go nuts - but enough reasonable people know what he said is true. He pretty much said it after Obozo was laying it on thick about the rest of us - so I think they will be happy that Joe called him out.
Joe made a quick human response that can be understood! Obozo has lied too many times.
It's outrageous that a President lie to the people. The congressman called him out on it. Let the cards fall where they may.
