I'm not saying this because he is a Democrat. If he were a Republican, I'd say the same thing. Personally, I'm rather irritated by all of these so called "scandals." I could care less what the guy is doing in his personal life. I don't care if he slept with any of those women or not. I don't care that Arnold has a "love child." So long as these public officials are not doing anything illegal or using government resources, they can do whatever they want when it comes to this sort of stuff.
Now yes, what Edwards did was illegal (allegedly) and it should be public knowledge.
But when it comes to matters that aren't illegal, I don't want to hear about it. If a politician is sleeping around on his wife, it's between them. If she divorces him, it may be a blurb on the news, but otherwise, who cares. We should hold our elected officials to higher standards, but those standards should only count towards the office/job they hold. Remember, these kind of things happen everyday all across the world- get over it. Joe Blow from down the street may be sleeping around on his wife, yet I don't care, nor does anyone else.
Remember, JFK slept around on his wife like it was going out of style. The media kept it to themselves because the president's personal life was none of their business. That's the way it should be.
If the ethics investigation finds that Weiner didn't do anything illegal, he shouldn't have to resign.
