Federalism- a form of government where a group of states, territories, etc., are governed by one central power. Federalists- a member of the Federalist party. Dual Federalism-the federal government and the statesâ government have separate, but equal, powers.
Dual federalism is the political theory that two different governments share sovereign power over a certain region or people. Generally this is the concept of balancing the scales of power between a large, sweeping government and a more local, centralized one. Usually, this involves some sort of federal authority and a state regime. The theory works as a type of check to ensure corruption does not impact either government. Rather than a form of cooperation, dual federalism is designed to create tension between the two forces. While the federal government mandates certain rules that cover a multitude of smaller governments, the state or local authority is responsible for nearly everything else.
