Did the U.S. constitution create a unitary system of government?

No, the U.S. Constitution did not create a unitary system of government; it established a federal system. In this federal structure, power is divided between the national and state governments, allowing both levels to have their own responsibilities and authority. This division aims to balance power and prevent any single entity from becoming too dominant. The Constitution provides specific enumerated powers to the federal government while reserving other powers for the states.
