Trump is largely the same person that he was four months ago, when the previous shutdown began. (If you need evidence, in recent days, he has abruptly announced plans to close and completely rebuild the Kennedy Center, suggested that he wants to “nationalize” the midterm elections, and threatened Iran with an attack from “a massive Armada.”) But his push to quickly resolve the latest shutdown highlights how much the political landscape on immigration has shifted following daily, videotaped clashes between masked federal agents and Minneapolis residents, two of whom were killed last month.
