We discussed the historical origins of federalism - a political system in which the national government shares power with the local (state) governments. The Constitution doesn't spell out the powers that the states are to have. States rights are vaguely mentioned in the 10th Amendment: "The powers not delegated to the United States by the Constitution , nor prohibited by it to the States, are reserved to the States respectively, or to the people. We will be discussing more about federal vs. state's rights in future classes.
