Regarding my earlier post, a friend from a libertarian think tank who's been around long enough to know where the bodies are buried writes,

As you note, the Kochs used to be a major funder of Citizens for a Sound Economy.  FreedomWorks was created after a major rift within that organization led to CSE's dissolution and the creation of the Koch-backed Americans For Prosperity on one side and FreedomWorks on the other.  Relations between the two groups are civil.  But, it'd have to be a cold day in Hell for the Kochs to be cozying up to FreedomWorks. . . . It's possible there's been some rapprochement in recent years.  But I rather doubt it.

This is roughly what I heard from others.  In other words, the central thesis of the article, that the Kochs are engaged in a broad astroturfing effort through Freedomworks, is most likely bunk.  That story should never have gone up with absolutely no verification of a fact so central to its core thesis.

If Santelli or Koch sues,  the rest of us big media bloggers are going to have to work hard to reassure our employers that we won't put them on the hook for a lawsuit.
