Obama is not some kind of Messiah, he is nothing more than a politician. Therefore, first and foremost he is Pro-Obama. He wants to get re-elected.
Right now, Wall Street is in the tank. He can make political hay pointing out the mistakes that have been made and taking shots at it....even though some of those mistakes carry the fingerprints of his own party. He signed on to a threatened fillibuster of additional regulation of Fannie and Freddie when he was a senator. Why not? After all he is a politician and they don't climb the ladder bucking their own party.
When the market rebounds, and at some point it will, he will attempt to take credit for it because he is a politician. He will say his new, warmed over Jimmy Carter policies saved the day. It is in his interest that the market rebounds.....not that he can do much to bring it about.
