From the crusades of George W. Bush to the shrill attacks of the "Tea Party" and the populist mobilization of Donald Trump: America's conservatives keep the USA on edge. For many Europeans, this is a disturbing phenomenon, as the combination of radical individualism, deep religiosity, and hyper-patriotism hardly exists in this form in their countries. The book traces the formation of a political movement that has moved from the fringes of political events in recent decades to the center of American politics - and ultimately questions the future of a party that was unable to stop the rise of the outsider Donald Trump.
