For the time being, I think former North Carolina senator and VP candidate John Edwards holds this dubious distinction.

As if having an extramarital affair on his terminally-ill wife weren't bad enough, the NY Times is reporting that Edwards is close to publicly admitting that he is the father of Rielle Hunter's baby daughter.

A former Edwards aide is saying that his boss wanted him to pose as the father's child. And now, that same aide is saying that Edwards promised to marry Hunter after Elizabeth Edwards dies.... in a rooftop ceremony with the Dave Matthews Band performing.

Say what you will about Bill Clinton. But for all of the headaches that he got from Whitewater and Monica Lewinsky, Clinton was able to rehabilitate and repair his reputation. I don't see how John Edwards will be able to do the same.
