I usually try to give books a fairer shake before DNF-ing, but at 75 pages in I was already starting to skip around, so I think it's safe to say that The Constitution Today isn't going to do it for me. It seems like there's a lot of valuable insight here, but the problem is the format: most of the book is not original content, but rather a collection of short articles that the author published over a span of ~20 years. He's organized them by branch of government and provided lengthy new introductions, but once you get into the articles themselves it's hard to stay engaged. For one thing, they're repetitive; unsurprisingly for articles written by the same person, on the same topic, but published years apart in different periodicals, similar arguments and phrases crop up again and again. When you're reading these back-to-back, it's frustratingly inefficient. For example, in the first chapter, we get:
"Put simply, Washington became father of his country in part because he was not father of his own children." (pg. 30)
"One key reason that George Washington became father of his country is that he was not father of any offspring." (pg. 34)
"George Washington became father of his country precisely because he was not father to any child who might seek to succeed him." (pg. 35)
It's an interesting point and a well-phrased one ... the first time you read it. By the third time, in the span of five pages, it's aggravating.
Then there are the drawbacks of articles that were written as immediate responses to events that are now in the rear-view mirror. Amar says in the introduction that he hopes including these throwbacks will justify his method by showing that constitutionally-based arguments usually win out over time. But an analysis of the constitutional qualifications of 2008's presidential candidates is just not as riveting when you already know who won. For another thing, because the articles are designed to be bite-sized, to make their point in the space of ten paragraphs, they hurl names and dates and court decisions at you relentlessly; when you read them back-to-back the effect is overwhelming. My brain checked out in protest. And then there's the issue of context. This is something that will vary from reader to reader, but as an adult in my twenties, I can't just fill in the context for electoral debates from 2000 from my own memory. Sure, I voted in that year's election ... in my kindergarten classroom, by circling my preferred candidate's picture in crayon. (I picked Bush because I liked his name better.) I need Amar, as the author, to do some of the legwork here. All of these issues could have been resolved if he took the main thrust of his arguments from these articles, and then reworked them into original content with better pacing and less repetition.
Finally, this book was published in 2016, before the election. Reading it in 2020, that might as well be ancient history in terms of the way the conversation about American politics and constitutionalism has changed in the last four years. That's no fault of the book's, of course, but it makes me hesitant to recommend it now.
