Beto O’Rourke is lost. The former Democratic congressman, who unsuccessfully challenged Ted Cruz in last year’s election, has spent the last few weeks in a confused and melancholy state. Something possessed him to live-stream a recent dental cleaning, perhaps the grossest introduction of a potential presidential candidate in the nation’s history. He gave an interview to the Washington Post where the only specific plank in his immigration platform was opposition to President Trump’s border wall. In the same interview, he mused that the Constitution may no longer apply to the United States, since we’re an “empire” with troops deployed around the globe and “trading agreements.”
