Over the past decade, conservative Christian public law firms have been some of the most active and aggressive litigators in the nation. Their efforts have impacted important policy areas including religion in the Public Square, school prayer, gay rights, 'family values' and abortion policy. But the Fundamentalist Christian/Evangelical social movement is not monolithic. In this probing and judicious work, Hacker explores and clarifies the influence of ideology on the goals and behavior of three leading conservative Christian law firms and how they differ in agendas and approach. He provides rich interview narratives that shed light on interest group behavior and how it is influenced by internal group characteristics.
