The march to the Trump presidency began in 1988, when Rush Limbaugh went national. Brian Rosenwald charts the transformation of AM radio entertainers into political kingmakers. By giving voice to the conservative base, they reshaped the Republican Party and fostered demand for a president who sounded as combative and hyperbolic as a talk show host.

At long last, Brian Rosenwald has filled a scholarly vacuum by offering a cogent, well-researched, and entertaining explanation of how Donald Trump was elected president. The conventional wisdom that Trump won by swinging 80,000 voters in Pennsylvania, Wisconsin, and Michigan might be factually accurate, but is too simplistic. Instead, Rosenwald proves that the outcome of the 2016 election was three decades in the making, made possible by the emergence of a candidate perfectly suited to capitalize on an environment created by the titans of talk radio. This is the book that provides proper context for the greatest election upset in modern American history.

Rejecting claims that the medium acted as a Republican puppet, [Rosenwald] describes a curious relationship between the Grand Old Party and talk radio hosts, one that has had seriously deleterious consequences for American political life.

[Rosenwald] argues that the profit motive radicalized talk radio and with it the Republican Party…Because conflict and scaremongering drove ratings and ratings drove profits, the more extreme the hosts became, the more listeners they gained, and the more money they made. As they amassed power and influence, the hosts could demand fealty from the politicians they were discussing every day.

Moving the discussion of contemporary conservative media out of the realm of shadowy conspiracy theory and into the sunlight of deeply researched historical investigation, Brian Rosenwald shows how right-wing talk radio moved from the margins to the mainstream and warped American politics in the process. This book will be of vital interest to anyone concerned about restoring the quality of American democratic debate.

Before there were social media echo chambers, before there was Fox News, there was Rush Limbaugh and his kin. Brian Rosenwald has told the definitive story of how a squad of outrageous, rule-breaking right-wing radio hosts set the Republican Party agenda and then overtook the party itself. Scholarly and yet eminently readable, this book is indispensable for understanding the world conservative media wrought.

Upending conventional wisdom, Brian Rosenwald’s deeply researched book offers an incisive account of how conservative talk radio transformed American politics, altering the relationships between Congressional leaders and rank-and-file members, between activists and the party establishment, and between the demands of entertainment and the process of policymaking.

The rise of conservative talk radio has changed American politics and American life, and Brian Rosenwald tells a careful and comprehensive story of its rise and its mushrooming influence. From Rush Limbaugh’s humble beginnings to the election of Donald Trump, Talk Radio’s America shows through careful research and subtle argument how talk radio moved well beyond entertainment and grievance to change the role and makeup of mainstream media, the kinds of stories Americans consume, and the pliable nature of truth. A superb guide to one of the most potent forces in modern political history.
