I would care if it's my girlfriend. I wouldn't care at all if it's your girlfriend, though, because it's none of my business.
What Weiner did was incredibly stupid, but he didn't actually break any laws (has anyone said they felt harassed?), so while I seriously question his judgement and definitely wouldn't vote to reelect him if I lived in his district, I don't see why he should resign if he doesn't want to. Plenty of politicians have had sex scandals involving, you know, actual sexual intercourse with someone other than their spouse, and they stuck around.
I agree. He did a stupid thing. He should be ashamed of himself and seek counseling for what seems to be a problem. However, if he didn't break any laws, why should he resign? After all, Bill Clinton did far more embarassing things, was threatened with impeachment, and didn't resign.
And I vote Republican! OY!
Besides, who really gives a crap about this mess, other than his wife?
