federalism

                                  Federalism allows the states in different locations of the country to enact laws that are better suited for the citizens that live there, while still maintaining one central government.  It also helps to regulate federal control over the people. Federalism also helps regulate internal control in the government. For example, the even distribution of the powers of all three branches. Its also has very shady corners when it comes to foreign affairs, however it keeps the government and America together from going into chaos.
