That’s the way Lou Cannon was once described on television. (Jay can’t remember exactly by whom, but he thinks it was Al Hunt.) Cannon, the veteran journalist and author, has written a slew of books about Reagan, beginning in the 1960s. Jay wanted to talk to him about the recent eruption over Reagan and race. (Jay himself wrote about the issue – quoting Cannon at length – here.) In addition to this question, Cannon discusses the Tea Party movement (2009-16), Donald Trump, and the Democratic presidential field.
