Charlie Pierce asks right question: Why did DNC leak the story?

[kpete]

. . . if I wanted to distract from the fact that Sanders on Thursday was endorsed by the Communication Workers of America, and by Democracy For America, this also would be exactly the kind of story I would want out there. . . .

There was some serious dumbassery involved on the part of the Sanders campaign, and the person most responsible has been sacked, so the story's over, right? The DNC could allow the Sanders campaign access to the data again. But what admittedly sends my thoughts up a grassy knoll is how this relatively minor blip made it to The Washington Post in the first place. After all, the bungling was with the vendor, and with the DNC for hiring the vendor, so wouldn't the smart play have been to keep this whole thing in-house? Also, if this story survives through the Saturday night debate, let alone becomes an issue therein, and if the Sanders campaign is shut out from the national party data for longer than this weekend, I'm going to be very, very suspicious. Devious and clumsy are, after all, the hallmarks of the DWS era.
