It’s a dilemma. Journalists can’t stop covering Trump, but we do him a big favor, and the public none, by magnifying his presence, analyzing the tone of his every utterance, depending on his every obscenity for sales and distraction. If Trump runs again, journalists would do better to follow the money that supports him. Report on the party that has come to embody him. Talk with the people who vote for him. Explore the conditions of their lives. Dig into the issues that move them. Trace the lies that beguile them. And when Trump says nothing new, ignore him.
