Not "instantly", huh?
If you think (like Cruz purports) that we can simply allow the illegals to stay here, and grant them some sort of quasi legal status, while forever barring the door to them gaining citizenship, you're either crooked or naive in the extreme.
No court in this country will allow an entire class of people to remain in a limbo of second class citizenship. They'll be made fully legal before the next presidential election. Say hello to the complete end of any political dominance by the rightful owners of America.
So tell me. What do you propose we do about the illegal alien situation in this country?
That's a tough nut to crack but we could start by ending the mass murders of the "rightful owners of America" in the womb. As Mark Steyn says: "The future belongs to those who show up."
