“This book is about a political force of unprecedented magnitude in American life,” The New Leviathan warned. It defined the ‘New Leviathan’ as “a network of billion-dollar tax-exempt foundations and advocacy think tanks that work in concert with government unions and grassroots radical groups to make up the organizational core of the political left.” When The New Leviathan: How the Left-Wing Money-Machine Shapes American Politics and Threatens America's Future arrived in 2012, it came as a warning from David Horowitz, one of the veterans of the New Left, and Jacob Laskin, a talented Front Page Magazine author, about the new form of the enemy and the kind of struggle that the conservative movement would face.
