A fast-paced, rollicking, behind-the-scenes account of how the GOP since the 1950s has encouraged and exploited extremism, bigotry, and paranoia to gain power, American Psychosis offers readers a brisk, can-you-believe-it journey through the netherworld of far-right irrationality and the Republican Party’s interactions with the darkest forces in America. In a compelling and thoroughly-researched narrative, Corn reveals the hidden history of how the Party of Lincoln forged alliances with extremists, kooks, racists, and conspiracy-mongers and fostered fear, anger, and resentment to win elections—and how this led to Donald Trump’s triumph and the transformation of the GOP into a Trump personality cult that foments and bolsters the crazy and dangerous excesses of the right.
