As disgusted as people were with Clinton when he left office, a few years later he was well-thought-of. Bush engendered nothing like that level of mockery, and history will be kind to him. Even Nixon is remembered as an otherwise-solid President who simply crossed a line in his partisan battles. LBJ for that matter, much as he hated JFK, still benefits from the afterglow of Camelot and is remembered in more or less favorable terms despite later revelations of his low character, vile temper, corruption, and personal cowardice while getting his ticket punched in WW2.
No, the only President in my lifetime who is still universally remembered by the public at large as truly and utterly sucking was Jimmy Carter. Obama's performance has not sunk to that low-water mark yet, but he still has a year and a half to attain it, and seems to be bending every effort toward that goal.
