He said that they all have to go back. That he will build a wall. That the "good ones" can come back. Coming back, with a wall in place and real border security, would require a new law relating to formerly illegal immigrants and which ones can come back. That is not going to result in a mass return of unskilled labor. Nor will it allow them to become citizens. Whatever is enacted, if anything, will have to go through Congress and be signed by the President. Or they don't return at all, and existing law continues to be operative.
In any event, you misrepresented, and continue to misrepresent, what he said. We get it. You love Cruz. Go vote for him and let's see what happens. Stop making false statements.
