One-time girlfriend-boyfriend, Ann Coulter, 47, an extremely-conservative right-wing Republican pundit and 'bomb thrower' and Bill Maher, 53, a true liberal, political comic, and voice of the people, are set to lock horns this week in a four-city American debate tour.  Las Vegas bookies give all debates to Coulter, as she plans to wear a super-pointy 1950s-era Playtex bra, that once kept Bill on the hook. Said Coulter, "He's one very horny liberal and a sucker when it comes to what nature gave me. I'll always beat him by two points," she said with a snicker!
