Beseiged by a $600,000 Karl Rove rave, presumptive Massachusetts U.S. Senate candidate Elizabeth Warren (D-Occupy This) has launched a rebuttal in the form of a one-minute bio ad (via Politico):

Opening: “I’m Elizabeth Warren. I’m running for the United States Senate. And before you hear a bunch of ridiculous attack ads, I wanna tell you who I am.”

Sorry, Prof. Warren. The corn is off the cob in the ridiculous attack ad arena.

But good luck keeping the Roveniks at bay.
