Other worrisome optics for Dems:
Amnesty for illegals trumps health care for kids (CHIP)
Amnesty for illegals trumps military readiness
As I noted on another thread, the GOP's best course may be to take Judge Alsop's ruling and run with it. Keep DACA in place for the 700,000 who already applied (as Judge Alsop has essentially ordered), and shut down further negotiations for enshrining DACA in legislation.
The negotiations so far suggest that Dems want to expand DACA to not only the several million additional folks who were eligible for the program, but haven't apply so far, but also to their parents. I've heard numbers of up to 9 million. Trump should accept the Judge's ruling and declare victory - DACA for 700,000, but not person more.
