Last week, when I sat down with Rep. Richard Hudson, the North Carolina lawmaker made a stunning admission. As chair of the National Republican Congressional Committee, Hudson’s job is to defend the G.O.P.’s narrow House majority. But when we discussed midterm messaging, he was insistent that the party had already fulfilled President Trump’s campaign promises. “We delivered almost the entire agenda already—all the promises he made, we’ve delivered,” he said. When I asked whether “we’ve done everything” was really the best campaign slogan, Hudson paused. “That’s a good question,” he said candidly. Republicans will come up with something, he added. “I promise you, we’ll have a campaign plan. We’ll give it some cool name, and we’ll take it to the voters.”
