I didn't watch much msnbc or listen to much Air America once both proved so incredibly biased during the primaries, but I caught and transcribed the two examples noted in my first post in this thread (on page 7) in just a few minutes of listening/viewing to Maddow:

Also, after one of the debates, Maddow said that an answer Hillary gave about her Iraq AUMF vote "insults me personally." Given the consistent bashing that Hillary got from Olbermann, Matthews, Russert, and company, and the sampling of comments I've encountered, I'd be quite surprised if these are close to the only ones.
