In our study of how U.S. Supreme Court nominations affect other parts of the president’s agenda, we had to work through the expectations and conventions of several different subfields in American politics. This became apparent during the review process when we had to respond to a wide array of comments. This case talks about some of the challenges associated with cross-subfield research. In addition, this study serves as a good example of event history analysis, a method useful for the study of how long it takes before a certain outcome occurs. In preparing the data for our model, we started with others’ replication data and extended it to fit the needs of our study. This case thereby focuses on addressing an array of concerns with doing cross-subfield research, using event history models, and using others’ data as a guide for new coding.
