Even Senator Kyl said in committee speeches and floor speeches that it's impractical to deport all 11+ million illegals in this country. Deporting them all, as he put it, would require buses put end-to-end stretching from the Mexican border near San Diego, all the way to Juneau, Alaska.
What exactly does Senator Kyl propose ? (Btw, I want to repeat that even though I've disagreed with him on immigration, he's a great senator. I wish he'd run for president.)
