The powers that are not federal.
All natural legislative authority remains with the States. All legislative and law enforcement matters dealing with individuals of the States lies with the States. The federal government may not legislate or enforce laws against individuals within the several States legally. The federal government was only delegated a few, very narrow, artificial legislative powers in order to settle matters of law among the States and between the United States and other foreign countries.
