Mahdi has “stepped away” but he has not “left his post”, It is a curious constitutional posture from what I understand. Zarfi’s government, people and policy program, are arguably dead on arrival. Both Ameri and Maliki oppose him. The Kurds have said that they will not support any PM designate without a Shia consensus favoring that candidate. While I put my money on an increase in value of the dinar, I must allow for the probability that Mahdi will stay until elections in 2022 if the/any government survives.
