“This ruling is catastrophic. This means people can come into the country in any number and the immigration laws cannot be enforced. It is a boon to demagoguing Democrats who will happily accommodate them for the votes.”
Nothing in the ruling prevents the Feds from continuing to enforce immigration laws. What it does though is inhibits cooperation from local law enforcement.
I’ve always been cautious about forcing states to uphold Federal immigration laws in the first place — for the same reason why state and local law enforcement officers cannot be obligated to enforce Federal gun laws.
