I want to know the answer to the following question:
What type of system is American Federalism?
All the background I'm provided with is that "In the dual-sovereign system of American federalism (actually tripartite because of the presence of Indian reservations), states are the plenary sovereigns, each with their own constitution, while the federal sovereign possesses only the limited supreme authority enumerated in the Constitution.". Is that enough to answer the question?
Answer: yes
