Harris - make America a 3rd world shithole
I am sorry that you misunderstand the supremacy clause.
The supremacy clause means only that state law can never override Federal law. It doesn't mean that states must enforce Federal Law. That is why there are Federal courts in every state.
It is the job off the Feds to enforce Federal law.
And if congress asks the States to provide the information they have on an individual, such as citizenship status and address, the States must comply.
