I'm curious. Can you name a current conservative candidate for the Republican nomination who shares your views on "amnesty"?
And trust me, I'm a conservative. But I don't think I want to expand the police presence by the factor of 10 to 100 that it would take to carry out a "deport them all" plan.
No matter what you think, these people are not going to volunteer to go back to Mexico. Not going to happen. You will have to find them, arrest them and ship them back. By the millions. Good luck with that.
You have no law enforcement unless you enforce the law.
