If Joe Biden wants to blindside his fellow Democrats at the first presidential primary debate next month, CNN has just given him the perfect opportunity. All he needs to do is declare his decision to run before the Oct. 13 debate takes place—even hours before—and he'll be given a podium to stand behind. According to debate criteria, candidates must average at least 1% in three polls released between Aug. 1 and Oct. 10 to be recognized, which means Lincoln Chafee, Hillary Clinton, Martin O'Malley, Bernie Sanders, Jim Webb, and Biden—should he run—are already eligible. Anderson Cooper will host the debate at 9pm ET. (The latest poll had good news for Ben Carson, not so great news for Clinton.)
