We all maybe miss the point.
While we should not care if our congressmen screw cows, goats, or chicken, as long as they formulate excellent public policy which is the thing that should matter to us, still Weiner has become a lighten rod for Public outrage because he broke American taboos.
Simply because that idiot could not keep his rocket in his pocket, he will, get hounded out of office.
In terms of scandals. Average Americans understand only two things, a scandal involving sex, or a scandal over money. And if the money scandal is not totally simple, the thief is likely to get off if slightly clever.
My best guess, long odds, Weiner is toast, and its already all over but the shouting. Even if Weiner did nothing illegal. And he does not even need to say he never had sex with that woman.
American's are a funny people, devoid of any rationality. But like sharks in water, we are all too willing to go into feeding frenzies. Because we are all holier than thou over issues that don't matter. But honor satisfied and Weiner removed, the amount of sexting over cell phones will just keep increasing.
