Federalism makes it so that a single state can't pass any ole' law because they can't contradict the federal law.Federalism in the United States is the constitutional relationship between U.S. state governments and the federal government of the United States(Wikipedia 1). It also makes the government have much more power than we realize.One of the clear benefits of a weaker federal government and stronger state governments is that the needs of each individual state are more easily managed. Alaska, Iowa, Rhode Island, and Florida are all very different states with very different needs, populations, and values; law that may make sense in New York might make little sense in Alabama(us conservatives 1). Lets say that a state wants to legalize marijuana federal law doesn't allow that to happen because it would have to go through judicial review in order for that state to make that law. Federalism and Judicial Review tie in together to make America run smoother.While the full powers of the judiciary were not completely expressed in the Constitution, precedent and future laws helped expand its role within the federal government.Source: Boundless. “Judicial Federalism.” Boundless Political Science.
