That's fine with me.
If they want to =keep using it= as "a prop", then that last thing they'll agree to is legislation that legalizes the daca's but also expedites the border wall.
This is what we want.
NO amnesty for dacas.
I'm not advocating that they all be "sent back". Probably not practical. Those with criminal records (of course) MUST be punished and then sent home.
Leave the dacas as their parents are -- illegal, in limbo, and never able to [legally] vote...
