That has become the stance of the amnesty crowd. Cruz, Rubio, and Trump are saying the same thing, i.e., build the war and then we will decide what to do with those already here. It is a way to deflect the question of what do we do with the 12 to 20 million lawbreakers already here..
But at least get the wall built, that’s more than anyone else is saying.
Personally I think it’s very easy to make them self-deport, Cut off the bennies, and punish the companies that hire them.
