Guess the biggest difference is that most past presidents were reluctant (Clinton the exception) to go before the camera while being observed by the american public. Our current president would literally destroy anyone standing between he and the camera. Obama had an excellent opportunity to do good. He was "green as a gourd", unskilled and knew nothing of the presidency (which is not unusual for a beginner). Unfortunately, he remains much the way he arrived. It's ridiculous that he cared so little that no effort was made to improve, learn or seek assistance. He has blown it!
