However, determining the extent to which municipalities are preempted is challenging. We overcome this by surveying a large sample of municipal officials from across the U.S. We find that officials from municipalities that are more ideologically distant from their state overall are more likely to report being preempted by their state government. Moreover, this pattern is driven by more liberal municipalities in both Republican and Democratic states reporting higher rates of preemption. Additionally, municipalities under unified state governments are more likely to report preemption, especially those under unified Republican control. These findings have important implications for the quality of representation in our federalist system and indicate that preemption is not just an issue between Republican states and liberal urban cities.This dataset underwent an independent verification process that replicated the tables and figures in the primary article. For the supplementary materials, verification was performed solely for the successful execution of code. The verification process was carried out by the Odum Institute for Research in Social Science at the University of North Carolina at Chapel Hill. <br></br> Note: To maintain the confidentiality of the participants, the authors cannot share the original data set. The authors shared the original data with Odum Institute for verification purposes. In Dataverse, they have posted a version of the data set with added noise to protect the confidentiality of the respondents. See the readme for more information.
