Final answer:
The power that the Constitution specifically denies to the federal government is the power to regulate interstate commerce.
Step-by-step explanation:
The power that the Constitution specifically denies to the federal government is the power to regulate interstate commerce. The Commerce Clause in the Constitution grants Congress the power to regulate commerce among the states. However, the Constitution also contains a provision called the Tenth Amendment, which reserves powers not delegated to the federal government to the states or the people. This means that any power not explicitly granted to the federal government, such as regulating intrastate commerce, is reserved for the states.
