Reagan's enduring value as a conservative icon stems from his resolute preaching of the conservative gospel, in words that still warm the hearts of the most zealous conservatives. Yet Reagan's value as a conservative model must begin with recognition of his flexibility in the pursuit of his conservative goals.
There has always been interest in certain phases and aspects of history - military history is a perennial bestseller, the Civil War, that sort of thing. But I think that there is a lot of interest in historical biography and what's generally called narrative history: history as story-telling.
In the academic world, biographies of these great figures of the past fell out of favor in the 1960s, when there was a turn toward social history, which meant the history of the voiceless and faceless. But the public at large never embraced the idea that these dead white guys should be abandoned.
Some years ago, I read Thomas Carlyle's history of the French Revolution, and I was very taken by the way he told the story, and it seemed as though I was right in the middle of things. And it took me a while to figure out how he achieved that effect, and one of the ways was to write it in the present tense.
The president of the United States from the 1940s until 2017 was considered the leader of the free world - probably the most powerful person in the world - not simply in terms of America's military might but in terms of the moral authority of the president. Donald Trump has largely abdicated that.
When the Constitution was written in 1787, there was this supposition that American politics would be above party. The people who would staff the positions in government would have the interests of the country, or at least their states and congressional districts, at heart, and so they wouldn't form permanent political parties.
To me, the puzzle of Ronald Reagan is how a comparatively ordinary man, someone with not extraordinary talent, accomplished such extraordinary results. At the age of 50, no one expected that this was going to be the guy who would become, at least in my interpretation, one of the two most important presidents of the 20th century.
