How do the candidates stand up in terms of character? For instance, Guiliani has had two divorces, one nasty, Fred Thompson has a bit of a reputation as a womaniser. Some candidates have flip-flopped over policy (the precise policy itself being irrelevant for this thread). Clinton gained a lot by standing by her husband, but has things like Whitewater. Edwards is seen as a vacuous lawyer. And so on.
So tell me of the candidates characters.
