It’s either:
1. A setup so that there never really is a vote on whether it’s a treaty or executive agreement. Since treaties require super majority and since Congress cannot assign its enumerated responsibilities nor encumber another Congress or Administration.
2. It’s all theater. The GOPe wanted it passed and rigged it so they couldn’t stop it.
3. Obama challenged them to take him on with both hands tied behind their backs — then he realized hey, both hands are already tied behind their backs.
One of the arguments made by the GOPe is that the Iran sanctions bills passed by Congress which date back to 1996 all include Presidential waivers (under the condition that such waivers are in the national interest).
So they take the position that even if they treated this capitulation as a treaty and voted it down, Zero would still use the waivers to kill the sanctions anyway.
Still, they should be voting it down as a treaty regardless. If nothing else that would strip the deal of its legitimacy while defending the Constitution, rather than aiding and abetting this fraud by the WH.
And there are many more powers Congress controls - they could block all funding of the UN, the IAEA, the State Department, or the entire government. Yet they choose to do NOTHING.
It would also be common sense if they won’t consider it a treaty to at least use the “nuclear option” to ensure a Senate vote. Yet even that move seems too much to ask of the GOPe, despite the Rats using the nuclear option at will to force thru all of their radical judges!
