anyone saying "be more objective, look at his failures etc." are forgetting how bad the average POTUS is. Obama being merely OK would promote him to the upper echelons.
Upper echelons yes, but absolutely NOT the top 10 which tends to be reserved more for those who go ALL the way one big issue and make it (such as LBJ and the Great Society, JFK and the Moon, FDR and the New Deal, Eisenhower and the Interstates)
Well LBJ did additionally go all the way in one
other "big issue", but not one that I would, err, support.
