Well, lefty blogs say lots of mean things about the newsmedia, so of course they're going to rally around the fraternity.
The biggest factor is probably people mistaking a strident tone for radical politics. Everyone keeps saying that the base is going farther left, that the Kossacks are pushing the party away from the center, etc. But who can list all the radical planks of the bloggy agenda? The only policies that would really represent a significant change are a single-payer healthcare system and gay marriage.
For the most part, the activist base just wants the Democratic Party to push back harder against the GOP agenda. Social Security, the bankruptcy rules, the estate tax, etc. Howard Dean was meant to be the leftist candidate, but it was because of his aggressive rhetoric, not his policies.
The Kos wing of the party is not radical, just oppositional. They support "moderate" candidates in Red States as a matter of tactics.
Phoenix Dark: What exactly are the main achievements of the 9-11 Inside Job movement at this point? What politicians court the movement? What organizations in this movement even try to affect elections? How is it even close to being equivalent to an anti-DLC movement?
What do you have, other than "I met these guys on the internet who said..." to make you believe this?
edit: Shut up, Diablos. You're not allowed to pull the "I'm so angry cause the public is so much dumber than me" bit. You're stupid. You read your books; you're still stupid.
