DACA already IS a temporary protection and thanks to the Texas lawsuit, it would still be at risk even if he left it in place. The only way this would be worth the while for Democrats is a USA or Dream Act...which doesn't leave people out and can eventually provide some sort of a pathway out of this mess.
