we're back with david, mira and newt gingrich. to the republican side of the equation in this book "double down" which is basically the new game change from 2012, the relationship between mitt romney and chris christie is fascinating to me because there is this admiration of a guy fighting on the part of mitt room knee and disgust because he was late all the time and worried about things in his background, ultimately, mitt romney didn't decide for chris christie. the question is, why does this stuff get leaked right now, and whether you think it hurts chris christie at this point, should he be a 2016 candidate? >> it's obvious. the romney people hit christie and those feelings eliminated he helped obama get reelected. i think it's nothing more than trying to undo christi as part of revenge in a sense.
