Not sure if I agree here. Taking the other side for sake of conversation:
Reps have ducked answering the tough questions here-- which is why and how Baraq is making his play. Until they confront this fact, things will get vituperative and the Reps usually lose when it comes to that.
First pass a stern, clear enforcement bill that neuters his BS claims of limited resources and takes away bureaucratic leeway identified by the SCOTUS decisions proffered by the OLC.
Whether he signs or not, the Reps should have the advantage-- yes?
