A vast left-wing conspiracy? The JournoList private server for left-wing big-wigs certainly seems that way:

POLITICO contacted nearly three dozen current JList members for this story. The majority either declined to comment or didn’t respond to interview requests — and then returned to JList to post items on why they wouldn’t be talking to POLITICO about what goes on there.

For all its high-profile membership — which includes Nobel Prize-winning columnist Paul Krugman; staffers from Newsweek, POLITICO, Huffington Post, The New Republic, The Nation and The New Yorker; policy wonks, academics and bloggers such as Klein and Matthew Yglesias — JList itself has received almost no attention from the media.

A LexisNexis search for JournoList reveals exactly nothing. Slate’s Mickey Kaus, a nonmember, may be the only professional writer to have referred to it “in print” more than once — albeit dismissively, as the “Klein Klub.”

Next time you wonder where the left gets all their lock-step talking points, you know where they probably originated. Left unsaid is who from the White House is involved. Or the mainstream media.
