I must note I get a lot of mail saying this is all about style—people pick on Mr. Trump because he isn’t smooth, doesn’t say the right words. “But we understand him.” “Get over these antiquated ideas of public dignity, we’re long past that.” But the problem is not style. A gruff, awkward, inelegant style wedded to maturity and seriousness of purpose would be powerful in America. Mr. Trump’s problem has to do with something deeper—showing forbearance, patience, sympathy; revealing the human qualities people appreciate seeing in a political leader because they suggest a reliable inner stature.

Meanwhile Steve Bannon, Mr. Trump’s former chief strategist, goes forward with at least partial support from the president and vows to bring down the Republican establishment. But Mr. Trump needs to build, not level. He needs a Republican House and Senate if for no other reason than one day Robert Mueller will file his report, and it will be leaked, and something will be in there because special counsels always get something. It is Republican majorities—the Republican establishment—that the president will need to help him. He will need the people he’d let Mr. Bannon purge.
