Rapaport and Dionne Jr. do an outstanding job of outlining the history, advocacy, criticism, and mechanics of a policy that, in short, is viewed with skepticism.
The concept of Universal voting, or civic duty voting, is navigated with ease as the authors deftly illustrate its success in Australia, Portugal, Peru, Belgium, and the like - even going as far to explain what methods, policies, and mechanics have historically benefitted or damaged voter turnout.
Unlike some policy books, 100% Democracy also openly and honestly addresses the shortcomings of its proposals, dedicating multiple chapters to acknowledging counterarguments, opposition to the policy, and where the opposition originates, all without taking a "holier than thou" voice to delegitimize the criticism. Instead, they take it on the chin and gently provide their defense.
I believe the authors may be over-optimistic and potentially cavalier about their claims to constitutional integrity of their arguments. They propose that universal voting could pass constitutional muster on limited precedent and arguments that I personally think do not strongly hold water. I admit, given that this book was originally written in 2022, years before we have seen the complete degradation of our democratic institutions under a particular President, my own cynicism is holding the text to a 2025 standard rather than only a few years ago.
Altogether, this is an outstanding entry into the concept of compulsory voting, which, at some times overoptimistic about feasibility, holds great integrity when highlighting both sides of a unique argument. I highly recommend to critics, advocates, and skeptics alike.
