Remember a few months back when Christopher Lee - the Republican Congressman from New York - was discovered to have posted a shirtless picture of himself online? What happened? Oh yeah, he resigned the very night that it came to light. His fellow Republicans weren't going to accept this sort of behavior or the distraction that would be associated with it. The Republicans have since lost Representative Lee's seat to the Democrats in the recent special election.
Now, what about Congressman Weiner. The night the issue appeared, he lied. Then as the scandal festered, he lied some more. Then it was starting to boil so he called in all the networks and lied again. As the lies inevitably failed, Weiner came out and admitted it. See, he's taking responsibility for his bad behavior. Well, only because he couldn't avoid it any longer. So, did the Democrats follow the Republican standard and demand Weiner resign posthaste? No. They're going with an ethics investigation. Even if Weiner did resign, the Democrats are unlikely to lose the seat.
Which party is holding its members to a higher standard of behavior?
