Trump Is Campaigning on a Platform of Abject Failure
President Trump has laid out his case for reelection. In a series of speeches over the past several days, the president has spelled out, or at least gestured toward, the major themes of his coming campaign. There will be other themes, to be sure—mostly, one presumes, attacks on Joe Biden—but the president's recent speeches in Tulsa, in Phoenix, and at Mount Rushmore all outline what appear to be
