Replication Data for: Textbook Pluralism to Modern Hyper-Pluralism: Interest Groups and Supreme Court Nominations, 1930-2017

We examine interest group involvement in Supreme Court nominations from 1930- 2017, finding dramatic shifts in the number and type of groups, as well as their choice of tactics. Whereas the early period was dominated by labor unions, ``core\" civil rights groups, and groups affiliated with the ``old right,\" the modern period is dominated by public interest/citizen groups and ``identity\" groups. We also find a shift from more traditional ``inside\" tactics to the heavy use of ``outside/grassroots\" mobilization tactics. Finally, we show that the calculus of mobilization has increasingly been based on a nominee's ideology over time.
