I'm not falling for it until I see him thwart the move for any kind of guest worker or amnesty program. it would be very easy to make some "lip service" comments about "rounding 'em up" that results in nothing, and then head fake and pass immigration legislation to make it worse. I am not pre-judging it yet mind you, but its something to watch out for.
I would say after saying this, he will have a hard time not opposing it.
