Not much.
Granted it's not all Obama's fault, he was put in one of the worse situations a president has faced ever, and there were a lot of things he just had no chance of changing or it was impossible to do so, and we would probably be worse off if the Republicans were in power or will be in power, but:
1. Obama has made his share of mistakes to and has screwed up things or has been lackluster in others.
2. Saying he is better than the Republicans would have been isn't saying much.
2. It's poor consolation considering people like me and I are still struggling and on the edge of disaster if one more bad thing comes our way we will be pushed right off that edge.
