 Two candidates made it to the runoff. Pazeshkian, a reformist parliamentarian and former heart surgeon, and Saeed Jalili, an ultra-conservative and former chief nuclear negotiator under former President Mahmoud Ahmadinejad. Barbara Slavin is an Iran expert at the Stimson Center in Washington, D.C. Pazeshkian has campaigned on promises that he would reduce efforts to enforce the hijab.
