The book exemplifies a paradox of aggregation. Individually, most authors (including me) answer “probably not.” Yet read every essay and close the book, and the impression you’re left with is more like “uh-oh.” Perhaps the reason is that the authors bring so much energy and varied perspective to describing the threats to constitutional democracy, and draw on different historical and comparative sources that reinforce each other. However, when explaining why those threats are likely to be countered, the authors converge on a series of familiar observations about the strength of our institutions and political culture. With each repetition, these observations sound more like hollow reassurances than irrefutable truths. Well, villains are always more interesting than heroes.
