With the Iranian nuclear deal fast approaching the deadline for congressional action, there’s a growing consensus, even among opponents of the agreement, that the fight in Congress is already over. The White House is just a few Senate votes shy of guaranteeing that any obstructing resolution passed by the Republican-controlled legislature will not survive a presidential veto, while the deal’s antagonists have zero momentum on their side.
