“How Democracies Dies” comes at exactly the right moment. We’re already awash in public indignation — what we desperately need is a sober, dispassionate look at the current state of affairs. Steven Levitsky and Daniel Ziblatt, two of the most respected scholars in the field of democracy studies, offer just that. Their book starts by giving us a readable but thorough look at democratic breakdowns in societies around the world. They then compare those incidents with current developments in the United States — and arrive at some disturbing conclusions.
