Sissy on Drum's "Slime Artists"

Sissy Willis discovers another endearing term for bloggers on reading Kevin Drum. I can't add much to what she says, because she says it beautifully, but I'll just point out the partisan focus of Drum's piece. Bloggers "campaigning against the established media" ... well, Sisu is right, that IS shocking. What's interesting to me is that the media (here and elsewhere) almost always identify anti-MSM blogs (or any they don't happen to agree with) as "right-wing" or "conservative". That is, they identify "right-wing" with "anti-media". Is this, then, an implicit admission of their own leftist bias?
