Washington (CNN)Bill Clinton criticized President Barack Obama's signature policy reform while on the stump for his wife, Democratic presidential nominee Hillary Clinton, calling Obamacare "the craziest thing in the world." Clinton told the crowd the insurance model "doesn't make sense" and "doesn't work here." "So you've got this crazy system where all the people who are out there busting it, sometimes 60 hours a week, wind up with their premiums doubled and their coverage cut in half. It's the craziest thing in the world," Clinton said.
