Not So Fast
Mark Sanford tried to have a hook up with his mistress while separated from his wife, away from prying eyes. He should have known that's impossible. Foolish? Yes. I wouldn't call that disgraced, unless you watch MSNBC. He did not resign, and was not impeached. And he did not use pubic money to hook up. And he's not running for office, he got elected.
As far as Weiner, what he did was also foolish, but not hurting anybody. I'm more concerned with his wife and her Muslim Brotherhood connections.
And Spitzer is a hypocritical scumbag. As a prosecutor, he hammered the "pimps" of escort agencies, while using those services himself. If he had just been caught using hookers, and not persecuting the business, I could forgive that. That's the equivalent of trolling for cock while being anti-gay. He was also an arrogant bully. Fuck him.
Lastly, that foot tapping episode reeked of overzealous law enforcement. If he actually verbally solicited the cop, that would have some validity. Don't know or care if he was actually a hypocritical cocksucker (literally and figuratively), but that bathroom bust scenario was B.S.
