Bill Adair, Pulitzer Prize winner, journalism professor, and founder of Politifact, presents an eye-opening and engaging history of political liars and a vision for how to make them stop.

Bill Adair knows a lie when he hears one. Since 2008, the site he founded, PolitiFact, has been the go-to spot for media members and political observers alike to seek the truth in an increasingly deceitful world. Since the site’s launching, politics’ tenuous relationship with the truth has only gotten weaker—and weirder.

In this groundbreaking book, Adair reveals how politicians lie and why. Relying on dozens of candid interviews with politicians, political operatives, and experts in misinformation, Adair reveals the patterns of lying, why Republicans do it more, and the consequences for our democracy. He goes behind the scenes to describe several episodes that reveal the motivations and tactics of the nation’s political liars, show the impact they have on people’s lives, and demonstrate how the problem began before Donald Trump and will continue after he’s gone. Adair examines how Republicans have tried to change the landscape to allow their lying by intimidating the news media, people in academia and government, and tech companies.
