‘Fraid I don't agree. States are going to have to go much further in resisting a tyrannical Federal government and asserting states rights. A state like California is going to admit everyone anyway and the Feds will either do nothing or actively encourage the actions. We actually need border check points between Arizona and California.
If the federal government continues to fail to enforce the laws, then effective secession is what will occur. Texas already does this, not sure what Arizona is waiting for.
