Interesting read, thanks for posting.
I wondered about how this might reflect on individual presidents and in my reading was reminded of history within my lifetime by this DailyKos article List of Reagan administration convictions.
I suspect that this reference to Reagan may inflame some conservative Republicans and I apologize as it is not my intent to inflame. It is my intent to examine illegal activities in Presidential administrations which is clearly different from scandalous behavior or the accusation of scandal (in my view).
It was interesting to me to discover in my research and reading that financial misbehavior/scandal is not uncommon but receives the least amount of press coverage. https://depts.washington.edu/uwiser/scandals.pdf
