I waited for the paperback edition of this book to come out, and I did well. This is a book best read with a bit of distance to the events described.
A history of the Supreme Court of the United States of America in recent times. Once an institution of minor rank, over the 20th century the Supreme Court transformed itself into a powerhouse of societal transformation, pushing the nation forward towards equality and the rule of law. Never mind that most of the justices were appointed by conservatives: they ended up veering sharply to the liberal side once appointed.
Unfortunately, though, the Supreme Court is still a deeply political institution. Its composition is determined by presidents who increasingly cannot choose based on legal merits but have to select someone who, first of all, will espouse a political opinion, and only secondarily is able to justify it in legal and rational terms.
