May 18 (UPI) -- Iranians began voting Friday in a presidential election between reformist President Hassan Rouhani and Ebharim Raisi that is closer than expected, two opinion polls indicate.
Although power in Iran rests largely in the ayatollah, Ali Khamenei, the outcome of the presidential race could lead to a more conservative government and jeopardy of the 2015 nuclear arms deal that has limited Iran as a Middle Eastern power.
