Mike Barnicle

Following Gov. Chris Christie (R-NJ) formally announcing his candidacy for president, Mike Barnicle and the Morning Joe panel discuss how Christie’s abrasive personality will be a factor in his run for the White House. “Over a long period of time, I don’t think [Gov. Christie’s personality] works quite as well. He is a terrific inside politician, one-on-one, but the abrasive stuff—‘sit down, shut up!’—I don’t think that flies,” says Mike.
