Book excerpt: This book goes beyond examining Donald Trump as a unique and controversial President to place his election in a historical and systematic perspective. It offers an analysis of the 2016 presidential nominations and election, the economic and demographic foundations of the election of Mr. Trump, the realignment of the party system, ideological polarization in American politics, the realities of a postindustrial society locked in a global economy, and the outlook for American democracy in the twenty-first century.
