Harding was not involved, however, in any of these scandals hence at best you could fault him for incompetency on this matter not "total" immorality. Again, when taken as a whole the money and power manipulations in these scandals were minimal compared to funny business which went on under FDR, LBJ, and Nixon. BTW, remember Truman and the Pendergast machine? In many of those other presidential scandals, unlike those under Harding, the presidents were directly involved.
...Harding is more history's choice as a bad president, than mine...
