I don't doubt Tribe has more brains than I do, but as a constitutional scholar, he's very much of the school of the "living" constitution. Or, the constitution only means what we want it to mean when we want it to mean that.
If we accept Tribe's interpretation, that means the President not longer needs Senate approval for appointments. Be careful what you wish for...
As for me, I'll go by the document that Tribe is bored with: "The President shall have Power to fill up all Vacancies that may happen during the Recess of the Senate, by granting Commissions which shall expire at the End of their next Session."
So in your literal land if one Republican shows up and wipes his ass, that's a session? Nah. I'd find your reasoning compelling if they showed up and actually do something...you know, like Nancy and all those dems who showed up to, ya know, actually fucking work! did, until then Obama did the right thing. Call/contact your republican comrades and tell them to start acting like fucking adults and this shit will stop. k?
