It may be a new low even for John Edwards. The National Enquirer, which broke the story about the former Dem veep nominee’s affair with an ex-campaign worker, now reports he went on a “sex-and-booze bender” after an apparently marriage-ending blowout with cancer-stricken wife Elizabeth. A divorced mom-of-two said Edwards hit on her “for four consecutive nights” at the Wilmington, NC, restaurant where she works. The unflattering portrait comes the same week a scathing book, “Game Change,” was released, describing the lengths Edwards went to to cover up his affair with Rielle Hunter, and quoting ex-aides who call him “a delusional egomaniac.”
