Answer:
-Federalism has excluded the power of the majority over the minority.
Federalism has kept the majorities of the United States from overriding the power of the minorities. For example, California and New York do not take all the decisions that affect Wyoming or Utah.
-Federalism has created a dual court system giving states the right to handle their own cases while reserving power for the federal court system.
Federalism means that each state has its own executive, legislative and judicial power. The state judicial power is represented by each state's court system, where the majority of the judicial matters of each state are handled, reserving only a few types of cases to the federal court system.
