David Corn of Mother Jones revealed tonight on the Rachel Maddow show that the already-infamous Mitt Romney “47%” video was recorded at a fund-raising event at the Hamptons home of equity trader Marc Leder.

Leder has been in the news before, and Mitt Romney’s religious right sponsors may not be pleased to find out about the other kinds of activities that take place at Leder’s mansion: Marc Leder Ends His Weekly Bashes in the Hamptons With Naked Guests Cavorting in the Pool and Peforming Public Sex Acts.

It was as if the Playboy Mansion met the East End at a wild party at private-equity titan Marc Leder’s Bridgehampton estate, where guests cavorted nude in the pool and performed sex acts, scantily dressed Russians danced on platforms and men twirled lit torches to a booming techno beat.

The divorced Sun Capital Partners honcho rented a sprawling beachfront mansion on Surf Side Road for $500,000 for the month of July. Leder’s weekly Friday and Saturday night parties have become the talk of the Hamptons — and he ended them in style last weekend with his wildest bash yet.

Oh yeah. This campaign is getting deep now.
