Federalism in the United States is the constitutional division of power between U.S. state governments and the federal government of the United States. The Constitution creates a federal system of government; people are subject to two sets of laws, those of the national government and those of the states. Federalism is an imporant tool to the consitution as it "shares power". The constitution was designed to guarantee a weak central government by federalism and created a strong legislature, an independent judiciary, and a weak executive to prevent a dictatorship.
