>>On the other hand, Harding was a crook, and Carter was an imbecile.<<
I agree with you on Carter, but Harding was not much of a crook when compared to modern standards. I think LBJ was a crook that was an order of magnitude greater(worse)than Harding. Harding was largely a do-nothing President. That would put him in the middle of the pack for me.
You've got a very valid point there. LBJ was a rotten President.
