President Obama 500 days in Office-- Lets discuss!

Right/wrong most Americans have a viewpoint on how well/badly the President is doing is job. Recently, as seen with the BP affair --loads of criticism, even from Democrats such as James Carville-- who says his response has been 'lackadaisical'. Others from the GOP have been equally harsh on what he has thus far accomplished. Are the criticisms realistic given what Mr. Obama has accomplished over all? But are driven by words: 'self-serving politics'?
