I don’t think he caved here. As other FReepers have pointed out he is putting DACA squarely on the shoulders of Congress which is the GOP. If they put their names to it, they’ll get primary’d easily the next time they are up. If they do manage to pass a bill and it goes to Trump’s desk he vetoes it. If it goes to the SC it gets shot down.
Make no mistake any DACA bill that makes it to his desk will be veto’d and the RINO’s that passed it will be hanging themselves.
My prediction is that Congress doesn’t pass a DACA bill, and in 6 months dreamers become illegal.
I’m not so sure about that veto.
