First, if MBW was diddling the votes, she'd be stupid to admit to the possibility

True enough. But this is not outside the realms of possibility. Have you ever seen those "world's stupidest criminals" shows? I saw one where a would-be robber tried to break a bulletproof plexiglass window with a cinderblock; it bounced off, hit his head, and knocked him unconscious :-)

And I agree that DailyKos tends to attract angry comments. I was lured there by this post, which was emailed to me by a friend, so I don't know where it originated. I'm not a regular visitor.
