Did Congress Daily Dine and Dash on Marc Ambinder?

If not, they must have done something else to tick him off. Why else would he do this ? We know The Atlantic is high-brow, but there’s no need to dump on CD . Unless they dumped on him first. Anyone know anything?

UPDATE: Wait!  Aren’t the Atlantic and Congress Daily owned by the same parent company?  If so, would this be the equivalent to a kick in the crotch from your older brother.
