How did we get here? And what do we do now? In the wake of the 2016 presidential election, even the most seasoned political pundits and policy wonks were left reeling. Brookings Senior Fellow Thomas E. Mann has co-authored a new book, One Nation After Trump: A Guide for the Perplexed, the Disillusioned, the Desperate, and the Not-Yet Deported, to answer both how President Trump came to be and where everyone else can go from here. Mann provides a roadmap to understand politics’ latest existential crisis, and a call to action to become more politically engaged.

Mann, along with E.J. Dionne and Norman Ornstein, contend that while Donald Trump’s personality and disposition are quite unique, the rise of “Trumpism” began decades ago. Their book provides a historical understanding of the political movement that has surprised nearly everyone.
