If you think what is happening to Weiner has not been orchestrated you are kidding yourself. Sure, he had little discretion here, but like you said, at least 75-100 other congressmen are trolling for sex ever day. Weiner crossed somebody, and they either had the goods on him already or got the goods on him. This thing has been orchestrated.
Somehow I just can't get all worked up over that possibility.
If you're nationally-known and you have the habit of broadcasting photos of your crotch to random thousands of people, eventually somebody will notice.
