Not necessarily. As I pointed out in my email to Manzullo, the Hispanic community has experienced a lot of angst over the recent ICE raids. Rumors keep flying whether true or not. I believe we can make the most of their fear.
I think if such legislation as I propose passes and becomes law we'll see a major exodus of illegals. Yes, many will stay but once the sources for work and illegal ID's begin to dry up they'll see the writing on the wall.
I have my concerns over a massive program of deportation. That will definitely cost a bundle (that's my only problem with it). My way, the costs will be relegated to those foolish enough to stay. The costs would be high only if the preponderance of illegals stay. I doubt that would happen.
