In exclusive interview with TIME, Berkshire Hathaway boss blasts the two ’12ers, Romney for his time at Bain and Gingrich for his dealings with OWS/Freddie Mac.

On Mitt: “I don’t like what private equity firms do in terms of taking out every dime they can and leveraging [companies] up so that they really aren’t equipped, in some cases, for the future.”

On Newt: “This whole business about Gingrich going down to Occupy and saying ‘they ought to be getting a job,’ that’s just…you know, maybe they can be historians for Freddie Mac, too, and make $600,000 a year.”

PLUS: Calls out Senate’s Buffett Rule Act, pledges to match voluntary contributions by Congress GOPers; “I’ll even go three for one for McConnell.”
