The Tenth Amendment confirms the presumptions of the Constitution which is mainly pointed at limiting the federal government. The Constitution begins with the presumption of ALL power in the states and the people. Our rights are not enumerated, they are presumed as expressed in the Declaration of Independence and the Ninth and Tenth Amendments.
The states and people DELEGATE certain ENUMERATED powers to the federal government via the Constitution. If the rights and powers are not delegated to the feds or prohibited to the states by the Constitution, they are presumed to belong to the states and the people.
The states have the constitutional right and power to nullify unconstitutional federal decisions based on the Supremacy Clause, confirmed by the Ninth and Tenth Amendments, and no constitutional prohibition of such against the states.
I think your mistaken on that.
