Chris Christie may have gotten more attention for his facial expression during Donald Trump’s Super Tuesday victory speech than at any point in his own campaign. Perhaps the governor wasn’t feeling well. Or perhaps he was discovering more than he wanted to know about the man he’d endorsed for the presidency of the United States.

Monday night before the big primaries, Christie had told his New Jersey radio audience, “I am the highest-level endorser that Donald Trump has had. I’m the person with the most experience in governing that is in his circle.” He said that there was “absolutely no question” that Trump listens to him.
