Every time a public figure uses the term “American exceptionalism,” ordinary Americans turn to my website. It’s number one for a quick answer to the question: “What is American exceptionalism?” My latest benefactor was Hillary Clinton, who used the term in a speech on 31 August. My website hits spiked. Until about 2010, few Americans had heard the term. Since then, its use has expanded exponentially. It is strange that such an inelegant term should be adopted by two major political parties when so many people had not a clue what it meant. Of course, one doesn’t have to use the term to believe in the underlying concept.
