When Newt Gingrich's second and now ex wife Marianne Gingrich spoke on Wednesday on ABC's "Nightline", she created the worst poster boy ever for the polyamory movement. The former Mrs. Gingrich said that Newt asked her for an open marriage when he revealed that for six years he had been sleeping with Callista Bisek, the woman who later became his third wife. "He said, 'Callista doesn’t care what I do,'" Marianne said in the interview. "He wanted an open marriage and I refused."
