Almost all agree that president Trump frittered away his bargaining power on the DACA issue by saying that he’ll revisit it if Congress can’t produce a bill acceptable to him, so short of saying that he was just kidding, Trump should shepherd the bill through both the House and Senate so that he could sign it, then if that wouldn’t happen, DACA will be cancelled, because the purple-tie dominated Congress wasn’t serious about a fix acceptable to both sides.
