In Iran, voters are at the polls today to elect a new president. Ebrahim Raisi, the conservative head of the judiciary and close ally of Supreme Leader Ayatollah Ali Khamenei, is widely expected to win. Raisi is under U.S. sanctions for his alleged involvement in the execution of political prisoners decades ago. The new president will succeed Hassan Rouhani at a crucial time, as talks continue to relaunch the Iran nuclear deal, from which the U.S. unilaterally withdrew in 2018 under President Trump, reimposing sweeping sanctions on Iran.
