Gang up?

I keep hearing pundits refer to the idea that the debate this weekend tipped the vote toward Clinton. Andrea Mitchell just said that she thinks a lot of voters thought Edwards and Obama "ganging up" on Clinton was unfair. That's just stupid. Sorry. Maybe Mitchell is right, maybe she's just grasping for anything to fill airtime, but if she's right, she's describing the reaction of foolish people. When there are two people who disagree with a third and they are on a stage talking about their disagreements, it's not "ganging up," it's debating. I hope like hell nobody actually made a decision on that ridiculous basis.
