States have no rights at all. All of their powers are derived from the people. And the people may not confer any power to the states OR the feds that they do not first posess.
"Every society has a right to fix the fundamental principles of its association, and to say to all individuals, that if they contemplate pursuits beyond the limits of these principles and involving dangers which the society chooses to avoid, they must go somewhere else for their exercise; that we want no citizens, and still less ephemeral and pseudo-citizens, on such terms. We may exclude them from our territory, as we do persons infected with disease." -- Thomas Jefferson
However, it also conveys no power to put up stop signs.. run the schools.. zoning.. etc.
States have no right to these things?
