The only decision this really affects is the plundering of someone else's Social Security money..
Other than that your premise is flawed and shows that the far left does not understand the Constitution..
Supremacy Clause
"
This Constitution, and the Laws of the United States which shall be made
in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the constitution or laws of any state to the contrary notwithstanding."
So states will have to comply
