Harding was a bit before my time, quite a long bit of time actually. My opinion of him can only be formed by what I have read about him. As you know, historical analysis changes over time.
As far as I know, Harding's aren't likely to get any better. You might want to say that he got lucky to die before all his scandals were exposed. Someone even tried defending him by claiming that he was probably too dumb to know how corrupt his Ohio gang really was. Anyway, it never fails to amaze me how overwhelmingly popular he must have been at least in 1920!
