A single-state budget directs billions of taxpayer dollars to carry out various political and policy goals. Governors as chief executives have the fiscal responsibility to construct budgets, the political desire to create public policy, and the institutional means to achieve these goals. They seek out opportunities to make substantial changes in public policy provided to them by interest groups. Different interest group environments across policy issues thereby motivate gubernatorial intervention with distinct short- and long-term rewards. Nearly three decades of data from all American states substantiates these claims and shows real consequences: Policy issues and their corresponding budgets that experience short-term shocks grow more slowly over time. American governors change the fiscal landscape of a state when they are motivated to intervene in a policy domain and are enticed by interest groups to use their institutional powers.
