Answer:
State and national governments share power.
Step-by-step explanation:
Federalism is a system of government in which the power and responsibility of a geographical area are divided or shared between a central government and states government (regions or provinces) with delimited self-governing authority. The Federal System varies from country to country, some give more power to the states and less to the government and vice-versa. Either way, this form of government tends to have a Constitution that serves as a guideline to regulate the states and the government's functions and powers and to resolve disputes.
