This book addresses the influence of the American religious Right on the 2016 presidential election campaign. It follows up on a series published in the late 1990s and early 2000s that went into hiatus from 2004 to 2016. The editors, Rozell (George Mason) and Wilcox (Georgetown), are distinguished scholars of religion and American politics. Contributors to this book study the dynamics of the religious Right in eight pivotal states. Their focus is on the role of interest groups during the primaries and general elections, but they also analyze the electoral strategies of the main campaigns. Contributors seek to explain the apparent anomaly of Christian support for the Trump candidacy. Their analysis is succinct and based on strong empirical research. Summing Up: Recommended. Upper-division undergraduates through faculty.
