Based on the excerpt, James Madison believed that federalism is needed in government because it allows for the division of powers between the federal government and the state governments. This division of powers helps to limit the power of both levels of government and prevents the concentration of power in one central authority. Madison argues that federalism is necessary for maintaining liberty and preventing tyranny, as it allows for a system of checks and balances and protects against any one branch or level of government becoming too powerful.
