Sid Blumenthal is not Off Message with this hogwash.
He's on message for the "Obama must lose in November so Hillary can take her rightful throne" crowd.
Just like when he was pimping smears from the VRWC to slime Obama, he is on message now.
It's just that the Democratic message differs greatly from the Clintonista message, and Sid is only nominally a Democrat.
Sid is a company guy for Clinton, Inc. He's not freelancing when he's trying to destroy the Democratic nominee.
