>How to send 10's of millions of illegals home by then when they are established in the USA and have nothing to go home to.
Simple. Install turn-o-matic number machine at border. Tell all beaners to take a number on the way out. All beaners still in the US after two weeks are subject to arrest, deportation and permanent ban from re-entry. Those that leave and take a number get a shot at immigrating LEGALLY in the order they left.
