LBJ Doesn't get enough 'credit' for the complete failure of his presidency and the long lasting negative effect on the country. Hell, the illegal immigration problem we have now can be directly pointed back at him..
LBJ - I would agree, but without Roosevelt laying the ground work, LBJ would not have been able to do as much harm as he did. Perhaps we can have a three way tie, Roosevelt/LBJ/Carter (or four way if you want to include Clinton).
