which amendment gives power to the states
According to this Holmesian logic, rather than the Tenth Amendment constraining the expansion of national power, national power feeds off the reserved powers of the States as national developments dictate. In other words, the reserved powers of the States are conditioned within the context of national power. Moreover, because the Tenth Amendment lacks sustainable substantive content, Supreme Court Justices have license to define the Statesâ reserved powers as their respective ideological proclivities dictate.
