IN THE FINAL weeks of his campaign, speaking to a “town hall” hosted by Univision, a Spanish-language television network, Donald Trump made a point he doesn’t make very often. Asked about the need for immigrant workers, he replied: “We want workers, and we want them to come in.” The problem, he said, was illegal immigration. “I want them in even more than you do,” he said. “And we’re going to make it so that people can come into our country legally.”
