Abstract
Donald Trump is a transgressive president elected by a minority of voters but elevated to the White House by a quintessential institution of American federalism, the Electoral College. However, the federal system otherwise poses significant barriers to transgressive behaviour because it is a complex mix of dualism, intergovernmental cooperation, and national coercion. The system’s constitutional dualism allows space for autonomous state policy-making. The system’s rule-bound and bureaucratic structures of intergovernmental policy implementation limit the ability of one president to substantially alter this cooperative dimension of the system. The long-run trend, though, is toward greater centralization and federal government coercion of state and local governments.
