We examine interest group involvement in Supreme Court nominations from 1930 to 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.
