If you believe Ralph Nader, Bill Clinton was a pretty good President. Sort of a garrulous Calvin Coolidge. Without the taciturn truthiness and more or less accidentally, due to lacking any moral principles whatever - but sort of.
It's the lack of moral principles thing that makes Hillary more dangerous than Bill. Not that she shares that lack. She actually has principles, those a Satanic cult might imbue. Put another way, Bill was too busy chasing skirts to be serious about policy. Hillary is deadly serious.
For Bill it's all about what he can do for him. For Hillary it's all about what she can do to you.
