Opponents of state restrictions on immigration have often thrown out the red herring that "you can't deport 12 million people." Of course Russell Pearce and other illegal immigration oponents in the legislature have never suggested deporting 12 million people. They have simply pointed out that if the laws are made less accommodating, the illegal aliens will deport themselves. I thought this was an interesting article from La Voz.
Ante las pocas probabilidades de que se apruebe una reforma migratoria a nivel federal y el endurecimiento de las leyes estatales contra de la inmigración ilegal, muchos indocumentados se preparan para regresar a sus países de origen.
That doesn't translate very well word for word, but it roughly says...
"With a low probability that the federal govenment will approve immigration reform and the enduring nature of state laws against illegal immigration, many undocumented aliens are preparing to return to their countries of origin."
