During the 2016 campaign, I received a phone call from an influential political journalist and author, who was soliciting my thoughts on Donald Trump. Trump’s rise in the Republican Party was still something of a shock, and he wanted to know the things I felt he should keep in mind as he went about the task of covering Trump. During a July 14, 2016, appearance on C-SPAN’s Washington Journal, for example, I responded to a pro-Trump caller who was upset that I opposed Trump despite my having been a Republican for my entire adult life and having served in the Reagan and George H. W. Bush administrations and the George W. Bush White House.
