I think I spelled it out in an earlier thread, but here I go again.
The US Supreme Court WILL stop any attempt at wholesale deportation. The fact that nothing has been done to deport those here is tantamount to amnesty as is in the Court’s eyes, and any law that would retroactively kick out those here for 2+ years would be seen as violating the Ex Post Facto provision in the US Constitution. The best we can hope for is that we can stop them from voting, kick them off of welfare, make it an incredibly long process for them to get green cards (20+ years), and restrict their ability to hold work in the US. We can, however, secure the border, end chain migration, kick the most recent migrants and criminal aliens out, and end the current policy on anchor babies.
So even if Congress and Ted Cruz decided to enforce the laws on the books, it would be as if the law did not exist up to that point based on lack of enforcement.
Where in the constitution does that 2+ years thing come from?
