As the Framers knew, we are unlikely to outgrow human nature. So what happens when we decide we’ve outgrown a Constitution designed to protect us from human nature’s foibles? The question arises, yet again, thanks to Senator Bob Corker. The Tennessee Republican, chairman of the Foreign Relations Committee, is author — along with Robert Menendez (D., N.J.) and Lindsey Graham (R., S.C.) — of a ballyhooed bipartisan bill that is being touted as the derailment of President Obama’s plan to trample congressional prerogatives en route to a calamitous “deal” that will facilitate jihadist Iran’s nuclear-weapons ambitions. (I use scare-quotes because the so-called deal is still a work in regress.) So guess who now supports this stalwart congressional resistance to our imperial president? Why none other than . . . yes . . . Barack Obama! You think maybe, just maybe, the Corker bill isn’t quite what it’s cracked up to be? You’d be right.
