The constitution enumerates specific federal powers

According to the tenth amendment, all powers not delegated to the Federal government and not prohibited to the States, are reserved to the States and the People respectively. This simply means that if the Constitution doesn’t give the Federal government the power to do something, it cannot legally do it and these powers are then deferred to the States and People respectively.
