The American system of federalism consists of the division of powers between the national government and state governments. It is characterized by dual sovereignty, where both levels of government have their own distinct powers and responsibilities. Here are some true statements about the American system of federalism:

1. Powers are divided between the federal government and the states: In a federal system, certain powers are delegated to the national government, while others are reserved for the states. This division of powers is outlined in the U.S. Constitution.

2. National government controls specific powers: The federal government has powers that are explicitly granted to it by the Constitution. These powers are often referred to as expressed or enumerated powers. For example, the federal government has the power to regulate interstate commerce, raise and maintain an army, and coin money.

3. States hold reserved powers: The states have powers that are not specifically given to the federal government, nor denied to them by the Constitution. These reserved powers include matters such as conducting elections, establishing local governments, and regulating intrastate commerce.

4. Supremacy of the Constitution: The U.S. Constitution is the supreme law of the land, and both the federal government and the states must abide by its provisions. If there is a conflict between federal and state laws, the Constitution generally takes precedence.

5. Cooperative relationship between levels of government: While the federal government holds certain powers, it often works in cooperation with the states to address various issues. This cooperative relationship is seen through programs like Medicaid and joint funding for infrastructure projects.

It's important to note that federalism in the United States is a complex system, and the distribution of powers can be influenced by judicial interpretation, political dynamics, and changing societal needs.
