Prohibition Is Here to Stay focuses on the Reverend Edward S. Shumaker, a Methodist minister who for nearly twenty-five years led Indiana's influential chapter of the Anti Saloon League. Shumaker was one of the most powerful men in Indiana in the fight against demon rum, and his influence extended well beyond the boundaries of the state during the late nineteenth and early twentieth centuries. Jason Lantzer uses Shumaker's life and work to shed new light on the rise and fall of Prohibition and to better understand and appreciate the interplay of religion and politics in American culture.

Drawing on Shumaker's personal papers as well as archival work, Lantzer argues that understanding the role of religious faith and in particular evangelical Protestantism is essential to understanding Prohibition. Shumaker's religious faith inspired his crusade against alcohol and his efforts to make the Indiana Anti Saloon League one of the strongest political pressure groups in the country. Lantzer argues that Edward Shumaker's life and the cause to which he devoted most of it were not aberrations but exemplars of central currents in American culture of the time. Lantzer also connects Shumaker and the prohibition movement in Indiana to larger issues of America's transition from a predominantly rural society to an urban culture, with the attendant fears of change, loss of values, the impact of industrialization, and foreign immigration.
