CONCLUSION America at a Crossroads

"Contributors nicely and incisively dissect recent national and state-level partisan shifts and examine the role citizen activism played. This book is strongly encouraged for those seeking to understand how American politics is shifting, and why political lessons taken as a given a decade ago might no longer apply." -- Seth Masket, Director, Center on American Politics, University of Denver "Skocpol and her talented team of collaborators have produced a treasure trove of rich empirical studies of the organizational and grassroots political developments that have helped transform contemporary American politics.ÂTogether, they shed light upon the stunning reversals of political fortune from Obama to Trump. Both an impressive scholarly achievement and a sobering and enlightening stage-setter for the high-stakes 2020 elections." -- Thomas E. Mann, Senior Fellow, Brookings Institution "Some of the best work anyone has done on why Trump prevailed in 2016 and what has happened since, the essays are must-reads for anyone who cares about the future of US politics and anyone interested in what is happening at the grassroots." -- EJ Dionne, author of Code Red "Some of the best work anyone has done on why Trump prevailed in 2016 and what has happened since, the essays are must-reads for anyone who cares about the future of US politics and anyone interested in what is happening at the grassroots." -E.J.
