President Trump’s decision to pull the nomination of Congresswoman Elise Stefanik to be ambassador to the United Nations strikes us as the better part of valor. It’s not just the slim-ness of the GOP’s margin of control in the House, though that alone, at least in our view, would justify keeping Ms. Stefanik there. It’s also that she’s one of those rare legislators who is strong on personality, principles, and policy.

Those qualities are going to be at a premium in the House as the administration gears up for what is sure to be a struggle to cut taxes and advance other legislative priorities. Mr. Trump has so far governed by Sharpie, which in our system of separated powers has its limits, as the president is learning. Exiling one of the most gifted Republican legislators to Turtle Bay would be like the Yankees trading Aaron Judge on Opening Day.
