It doesn’t matter if the deal is voted be disapproved. Obama will veto Congress’ disapproval. This is the upside down logic Ted Cruz pointed out months back that Corker was so wrongheaded to package the Iran deal in this way because it would entail a 2/3’s vote in both chambers to override Obama’s veto.
Whereas if it had been crafted as a treaty as it should have been, it would have taken 2/3’s of the Senate to approve it.
I doubt, though, it’ll get enough votes to override a veto.
