Gubernatorial Veto Powers and the Size of Legislative Coalitions

Few political institutions are as central to theories of lawmaking as the executive veto. Despite its importance, institutional continuity at the national level has precluded identification of empirical effects of the veto on legislative behavior. We address this limitation and present evidence from the states demonstrating how the veto affects the formation of legislative coalitions and, indirectly, executive influence over policymaking. We find consistent evidence that the presence and strength of gubernatorial veto powers affect the lawmaking behavior of state legislatures. Our analysis shows how institutional provisions condition executives' ability to affect policy outcomes in separation‐of‐powers systems.
