To summarize, the Constitution puts the onus on the president to find 67 Senate votes to approve an international agreement, making it virtually impossible to ratify an ill-advised deal. The Corker bill puts the onus on Congress to muster 67 votes to block an agreement.
Under the Constitution, Obama’s Iran deal would not have a prayer. Under the Corker bill, it would sail through. And once again, it would be Republicans first ensuring that self-destruction is imposed on us, then striking the pose of dogged opponents by casting futile nay votes.
This is not how our system works. Congress is supposed to make the laws we live under. It is the first branch of government, not a rubber-stamping Supreme Soviet.
