Question

Quizplus · Accepted Answer

Dual federalism is often described as a layer cake because the powers and responsibilities of the national and state governments are clearly separate and distinct, just like the different layers of a cake. In this system, the national government has its specific responsibilities and functions, and the state governments have their own. It is also said to emphasize the federal nature of the U.S. government, which is composed of multiple layers of power and authority.
