Secure the borders. Don't talk to me about anything else, I don't want to hear any new whizbang immigration policy proposals until you secure the borders. If you can't secure the borders, why should I trust you with anything else?
If you can't secure the borders, nothing will work. All this talk of "policy" is moot.
Besides, we have laws now to deal with the problem and they are not being enforced. The executive branch of the federal government is not providing the resources to enforce current law. Which is its constitutional duty.
I see no reason to believe that that will change regardless of any law passed by congress.
