After eight years of covering Donald, too many journalists have gotten into the habit of seeing strategy in his crude and instinctive behavior. The truth is quite simple--Donald can’t help himself. When it comes to him, we shouldn’t overthink it. He is exactly what he seems: a racist, a misogynist, a liar. He is a bully who has no business getting anywhere near the White House. His pulling out of the debate should remind us that he is also a monumental coward.
