Hey, let's slow down immigration too. You know recent immigrants rarely vote Republican no matter what the Repubs do. Even Sen Amnesty McCain couldn't change that basic fact.
Immigration these days is largely about cheap labor anyway. It would truly help the entire country except employers and Democrats to reduce BOTH legal and illegal immigration. Don't believe ANY labor shortage claim. Why do H-1B, J-1 etc come overwhelmingly from low wage countries such as India (forget Japan and West Europe)? The obvious answer: cheap labor!!
