Well, there's a difference when Democrats do it (other than when Democrats do it that most of the time it's with women). Republicans (not all, but most) have taken the high road and have embraced the "family values" and claimed to be the good/moral/Christian party and have painted the Democrats as nothing but a bunch of immoral hippies who support the homosexual agenda and want to destroy the "sanctity of marriage," so it seems only appropriate for the Republicans to get all the glory when this happens because it exposes their hypocrisy of not practicing what they preach.
When you campaign on being the party that supports "traditional marriage" and how homosexuality is a sin/abomination that "threatens" your marriage, when you're caught committing a sin that endangers your own marriage, it just makes you a hypocrite, and the public has a right to know. Committing adultery is not only a sin but it's breaking one of the Ten Commandments, and divorce is also an abomination in the same respect as homosexuality, according to their interpretations of the Bible. Why condone one sin and not another? From my understanding of the Bible, no one sin is greater in the eyes of God than another. Hypocrisy at its best.
Lee just adds to the ever-growing list of family values Republicans to have their hypocrisy exposed: Souder, Ensign, Sanford, Craig, Foley, someone help me I've lost track. Oh, he wasn't a politician per se but that one anti-gay doctor who was caught with an escort from RentBoy.com. I guess we could also include Ted Haggard in here, too.
Focus on your damn family before you try to tell me how to raise mine or what mine should consist of.
But yeah, John Edwards is a sleazeball for what he did to Elizabeth. No excusing that. And poor Bill. The man got one blowjob and the Republicans still vilify him for that. Hillary forgave him; why can't you? I don't know who the other two guys are; I think they may be before my time.
