Christie is loved by the left. Bill Maher, Saturday Night Live and every liberal outlet loves Christie because he stuck it to Romney a week before the election.
Christie knew what he was doing. There's nothing wrong with being cordial to the President but Christie gave him a huge bear hug. All the photo ops of him and Obama staring into each others eyes was strictly political. John McCain thought he was loved by liberals and then when he ran against king obama, he was called everything but a child of god.
