Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right
By Jane Mayer
In 1980 Charles and David Koch decided they would spend vast amounts of their fortune to elect conservatives to all levels of government, and the world of American politics has never been the same.
Mayer spent five years looking into the Koch brothers’ activities, and the result is this thoroughly investigated, well-documented book.
It cannot have been easy to uncover the workings of so secretive an operation, but Mayer has come as close to doing it as anyone is likely to anytime soon.
