Krauthammer: Christie’s Attack on Rubio a ‘Political Suicide Attack’

BAIER: "Let's start with Chris Christie and Carly Fiorina stepping aside. Obviously Christie had to have a good moment in New Hampshire. Despite the debate where he took down Marco Rubio, he didn't have the benefit." 
KRAUTHAMMER: "Well actually that's happened before. In other races when you're in a multi-candidate race, you can score a big hit on somebody but that doesn't guarantee you're going to succeed. In fact often it hurts you as well. What happened to Chris Christie was a political suicide attack, where he looked a little bit, I thought, overbearing. But even if hit no effect on him, it didn't help him. By bringing down Rubio, which Rubio admitted, it helped all of the other so-called mainstream candidates."
