PROFESSOR JACOBSON TO POLITICO: Show Us Your Sources Or Shut Up! With a RatherGate reference. He’s absolutely right that you can’t trust MSM on political scandals involving Republicans. Or, as the John Edwards affair demonstrates, Democrats.

UPDATE: More specifics in this PJ Media report, though I’d still like to see names named, even from people I trust.

ANOTHER UPDATE: And, apparently, I was right to want more specifics. See the correction.
