Explanation:

The federal government and states in the United States have some concurrent powers (including regulating elections, taxation, borrowing money, establishing courts, and regulating commercial activities).  There are exclusive powers, which the U.S. Constitution empowered the federal government through Congress to manage.  Generally, state governments have the power to regulate all matters within their state boundaries.  However, the limitation comes when the states make laws that conflict with the laws of the federal government.
