I've been thinking about Edwards over the last 24 hours and I cannot figure out one little tidbit:

Why come forth now? You've managed to keep this under the rug for more than two years..........after the Enquirer had it all over the front page........and you've been reasonably successful at doing so.

Do you suddenly get a catharsis and have to offer up yourself to the country because you can't keep in inside any longer?

It's probably more likely that the mainstream press was going to run with it..........but, even if they did.........he could just remain in denial and there would be no conclusive proof unless the woman divulged the goods. He'd be in a better position with plausable denial than he would with an admission.
