My reaction to this....
Edwards tried to cover up a shameful part of his life, he apparently told his wife and family almost immediately (which was the right thing to do).
Having said that... THANK F**K! He isn't the nominee.
Had he said, "That's between myself and my wife," or "I'm not going to answer that," or, heaven forbid, told the truth, who would care? I wouldn't.
This isn't about Edwards having an affair, it's about him lying about it. Neither McCain nor Obama have a spotless moral record, but they are both up from about it.
