Trump's comments are erratic, but I think at bottom he is very disciplined and always on his message: "I win." Everything he does and says builds on this same core pitch, which he laid out in his opening campaign speech:
Do you feel like a loser? Well, guess what, you should. You are losing. We are losing. To the Mexicans. To the Chinese. To Iran. To bossy women. To Everybody. It is not morning in America; we suck right now. You suck.
