What does the doctrine of dual federalism maintain?

Question

Quizplus · Accepted Answer

The doctrine of dual federalism maintains that the national government and the states have authority over defined and mutually exclusive policy areas. This means that the national government only has authority over certain policy areas, while the states have authority over others, and each is separate and distinct from the other. This doctrine was prevalent in the United States during the 19th century and early 20th century, but has been largely replaced by cooperative federalism in which both levels of government work together to address policy issues.
