>I don't think we want to live in a world where absolute moral purity (as determined by the most vocal, biased critics of a given person) is required to hold public office.

Don't worry, you live in a world where a man with a well documented decades-long laundry list of scandals and faux-pas can brag on tape about how he can get away with molesting young women because of how rich he is and still get elected President.

I'm actually wondering what you could effectively blackmail an American politician with, given how little Americans seem to care about the morality of their leaders. Maybe just the eponymous "dead girl or live boy," but then you have the Kennedys...
