CNN’s New Day on Friday promoted the gushy new HBO documentary on John McCain, with substitute host David Briggs lamenting that President Trump “perpetuated...that John McCain is in a sense almost a traitor to the Republican Party.” Peter Kunhardt, the HBO film’s creator, bizarrely claimed the hallmark of McCain’s career is “the consistency of his message.” But he also said the “culmination” of the film is McCain flip-flopping on the repeal of Obamacare.
