Works for me.
Ike had "Operation Wetback" to deport illegals. Successful. All you really have to do is cut them off from the $$$ and they'll go home on their own. Arrest, try, and jail the employers that knowingly hire them and don't allow them to receive any government aid and they'll all leave. There will be exceptions, but mostly they'll go home and they will not come here when there is no opportunity.
They are here and they keep coming because the republicans want them.
