Under the Constitution the principle of federalism is the reason that power and responsibility are?

Under the Constitution, the principle of federalism establishes a division of power and responsibilities between the national and state governments. This framework allows for a balance, where the federal government handles issues of national significance, while states manage local matters. Federalism promotes a system of checks and balances, enabling both levels of government to function effectively while preserving individual liberties. Ultimately, it allows for diverse governance that can address the unique needs of different regions.
