One way the Constitution guards against tyranny is Federalism. Federalism is just a fancy word for the powers given to the states, to the central government, and powers the two share. Document A states that the central government can regulate trade, conduct foreign relations and declare war. The states can set up local governments, hold elections and establish schools. As James Madison said, “The different governments will each control each other, at the same time that each will be controlled by itself.” What James Madison is trying to say is that the central and state governments have enough power that they don’t control everything. The central government has enough power to help some of the country’s major needs and the state government has enough power to help the state’s needs because the state’s needs may be more specific. From this, you may conclude that dividing powers between the central and state governments prevents tyranny.
