There is no reason to doubt that outcome.
Sure, a few Democrats will “vote their conscience” and not support the “agreement”, but the Democrat party whips (what a quaintly descriptive term!) will make sure that the two-thirds majority requirement to override a veto will not occur in either the House or Senate, and there may not even be enough votes to override a filibuster in the Senate, by a matter of maybe only a vote or two, but the discipline will not be relaxed if it comes down to a close vote.
Current Occupant wins. As do the Iranians.
Was there ever any doubt?
Corker made sure it would be agreed to...GOP-e strikes again for Obama.
