Forcing themselves to later vote with a veto-proof majority is one of the absolute dumbest things I’ve seen in a long time. Unreal.
Unless of course the objective all along was to throw away our security and give a bunch of money to Iran, and later pretend that they were powerless to stop it. Again, they were all for it before they were against it, I guess.
That depends on your perspective. If you are a member of Congress who shirks from responsibility (but I repeat myself) it's perfect. You vote for the Corker Capitulation® when no one is paying attention then grandstand by casting a now meaningless vote against the agreement when everyone is watching. Under Boehner and McConnell, the GOPe having been milking this kind of scam with cloture and rules votes for all they're worth.
The Republicans set this up so the deal will be guaranteed to go through, and they can PRETEND to be against it. The truth is, they sold out completely. They are now as relevant as the Roman Senators when they found a new member of their “elite debating society” was a living breathing Donkey.
