Oh, I think I'm going to throw up. The New Yorker profiles Mark Halperin and The Note. Watch as your political discourse is debased! Enjoy seeing policy decisions trivialized! Guffaw in delight as the meta-wankery descends to depths heretofore unforeseen!

There's also a bit of the usual revisionist history when it comes to the Dean campaign, and this interesting little tidbit (later implicitly answered in the same article.)

During the Democratic primary season, the Howard Dean campaign spent months futilely trying to find out who kept sending Halperin its internal memoranda.

*cough* McMahon *cough*.
