On November 8, 2016, American voters elected Donald J. Trump, an authoritarian white nationalist with what is likely an undiagnosed personality disorder, to become the 45th President of the United States. This book analyses how this happened by focusing on who Trump is, who his supporters are, and the role of the media, right-wing Christians, and the Republican Party in making Trump's victory possible. It concludes with an analysis of this phenomenon as America's version of right-wing populism and illustrates how it poses a threat to democracy.
