Cohen, Struthers, MacKenzie, and Shugart publish in PRQ on interest group influence in California

Recent PhD Alex Cohen, along with UC Davis PhD alumni Cory Struthers and Professors Scott MacKenzie and Matthew Shugart, have published a new article in Political Research Quarterly, studying the effectiveness of intermittent advocacy and lobbying on climate-related bill outcomes in the California State Legislature. The authors develop an index of interest group diversity and show that letters of support from a diverse set of small, less politically active groups increase the likelihood that a bill passes committee. These findings illuminate how advocacy tactics differ by organization type and demonstrate that groups that lack capacity to intensively lobby can influence legislative outcomes. https://journals.sagepub.com/doi/10.1177/10659129261455783
