Answer:
The Supremacy Clause, which is found in Article VI of the United States Constitution, establishes that federal laws and treaties are the supreme law of the land. This means that if there is a conflict between a federal law or treaty and a state law, the federal law or treaty will prevail. This gives the federal government more power than the states in certain areas, as state laws must be in compliance with federal laws and cannot contradict them. Additionally, the Supremacy Clause also establishes that federal courts have the authority to interpret and enforce federal laws and treaties, and that state courts must follow federal law when interpreting and enforcing state laws. This further enhances the power of the federal government over the states. Overall, the Supremacy Clause helps to ensure that the United States operates as a unified nation under a single system of laws, rather than as a collection of separate and potentially conflicting state laws.
