This book provides unprecedented information about the rising tide of Evangelical political activists on the right and the rising tide of Secular political activists on the left. 'God gap' scholarship argues that Evangelicals and Seculars captured opposing parties, and created a religious divide between the 'Godless' and the 'pious'. This book introduces a new paradigm for understanding change among political activists - the representation-based model. This model offers a new way of looking at recent trends that reveals that basic demographic forces matter far more when it comes to understanding the rise of Evangelical Republican activists and Secular Democratic activists, and that mobilization matters far less. This book argues that whether one is religious is not the driving force in American politics. Instead, it argues that recent trends are a function of basic social and political changes within long-standing religious traditions.
