Exactly. If we consider us a nation of laws, then we should enforce our laws. Illegal is illegal. The answer is simple: deport them.
Which remains an option, after self-deportation has taken care of the bulk of the problem.
Cruz is merely saying "First things first. Second things second."
There will be plenty of illegals left after Trump's initial deportation, as well, and the very same decision will have to be faced.
I want them all gone, too -- but that may not be possible.
