What is the concept of marble cake federalism?

Marble cake federalism is a concept that describes the cooperative relationship between the national government and state governments in the United States. It emphasizes the blending and intermingling of powers and responsibilities between the two levels of government, rather than a strict separation. This concept suggests that the national and state governments work together to address policy issues and share responsibilities, resulting in a more unified and integrated system of governance.
