Under the tenth amendment what powers that are not delegated to the federal government are reserved for the states. Now if states don't have any rights, as some believe, then how can there be any powers reserved for the states under the tenth amendment? Its impossible for them to have zero powers because the tenth amendment makes it clear that there are powers reserved for the states. What those powers are are subject to debate but I think the tenth amendment makes it clear that states have all powers minus those delegated to the federal government and things prohibited to them. Thats a very narrow list of prohibitions against the states so states actually have 99.99999999% of all conceivable powers while the federal government is limited to things delegated to it in the constitution.
