They’re not going anywhere.
That is loser talk. Congress several times rejected DACA, said No. Obama illegally give them temporary amnesty--free public benefits and job permits. The court should recognize the illegality of this, confirm Trump AND Congress's end to DACA and after that there is nothing left except to deport them as their permits expire. They should say a gracious thank you for the education, healthcare, and public benefits they got, go home with that to fix their home countries. One million American educated young adults will have bigger impact on the cesspool countries than any financial aid package. Big impact.
No they are not. They will be a bargaining chip in exchange for Marxist rat Democrat support for border control.
