left and right, as well as the rise of outsider politicians such as Senator Bernie Sanders, takes place during the Clinton, G.W. Bush, Obama, and Trump administrations. During each of these eras, activists experienced shifting opportunities that they interpreted through the telling of stories. These narratives of opportunity encouraged participation in particular forms of grassroots mobilization, which then affected the outcome of each era. This has had lasting effects on the development of healthcare policy in the United States. In this book, Hern conducts a political ethnographic analysis in which she uses historical records, interviews, and participant observation to tell the story of the Single Payer Movement, establish the lessons that can be learned from this history, and develop a framework¿the Environment of Opportunity Model¿that involves a holistic understanding of social movement activity through the analysis of narrative practice.
