**An analysis of demagogues in American political history and an argument for restoring the constitutional safeguards to protect against them.** **“It is hard to imagine understanding the Trump presidency and its significance without reading this book.” —Bob Bauer, former Chief Counsel to President Barack Obama** **A* ** **New York Times Book Review*** **Editor’s Pick** **What Happens to Democracy When a Demagogue Comes to Power?** What—and who—is a demagogue? How did America’s Founders envision the presidency? What should a constitutional democracy look like—and how can it be fixed when it appears to be broken? The extraordinary negative reaction to Trump’s election—by conservative intellectuals, liberals, Democrats, and global leaders alike—goes beyond ordinary partisan and policy disagreements. It reflected genuine fear about the vitality of our constitutional system. The Founders, reaching back to classical precedents, feared that their experiment in mass self-government could produce a demagogue: a charismatic ruler who would gain and hold on to power by manipulating the public rather than by advancing the public good. President Trump, who has played to the mob and attacked institutions from the judiciary to the press, appears to embody these ideas. How can we move past his rhetoric and maintain faith in our great nation? In *The Demagogue’s Playbook* , acclaimed legal scholar Eric A. Posner offers a blueprint for how America can prevent the rise of another demagogue and protect the features of a democracy that help it thrive—and restore national greatness, for one and all. **“Cuts through the hyperbole and hysteria that often distorts assessments of our republic, particularly at this time.” —Alan Taylor, winner of the 2014 Pulitzer Prize for History** **“An important read for anyone concerned about the fate of American democracy.” —Steven Levitsky, co-author of* ** **How Democracies Die***
