Carly Fiorina supporters are criticizing CNN's debate criteria that could prevent the former Hewlett-Packard CEO from grabbing a spot on the main stage at the second debate despite her surging poll numbers. It's a similar argument that Larry Sabato, director of the University of Virginia's Center for Politics, has made. He said that CNN's methodology isn't just hurting Fiorina -- but also other candidates who weren't on the main stage at the first debate.
