However, if no candidate reaches this threshold, a run-off election will be carried out between the two presidential hopefuls who receive the highest number of votes. In that regard, Bayram Sinkaya, a prominent academic and expert on Iran, commented on the matter to Daily Sabah and said that neither Hashemitaba nor Mirsalam has a good chance of winning the elections, noting that all of the traditional conservatives, technocrats as well as reformists and supporters of former President Akbar Hashemi Rafsanjani have gathered around Rouhani. U.S. President Donald Trump's tougher stance on Iran has stoked concern as well, though his administration this week took a key step toward preserving the Obama-era nuclear deal.
Layla Daryafarghi, a 19-year-old journalism student, was 11 during the 2009 crackdown.
Raisi has described voters' choice as one between "inefficiency" and "efficiency".
Under Iran's constitution, the supreme leader has final say on all state matters.
With the exception of the third presidential debate in which candidates accused each other of lying and corruption, this year's Iranian presidential election has been relatively calm in comparison to the last two elections.
After voting, Raisi told journalists that all should "completely surrender to the result of the election". This year, Iranians appear unlikely to surge into the streets even if Mr. Khamenei fixes the vote in order to install Mr. Raisi, who is rumored to be a potential successor to the 77-year-old supreme leader.
He characterized those segments as "a young, modern Iranian population eager for change, and an entrenched, dogmatic military and clerical establishment eager to crush change". Indirectly, Ghalibaf suggests the nuclear deal with the West was a kind of Qajar-era concession.
The election is the first since the landmark nuclear deal in 2015 that resulted in significant limits on Tehran's most sensitive nuclear activities, which many in the West believed were part of an effort to build atomic weapons, in exchange for sanctions relief.
Inflation is down dramatically and growth is up, but so is unemployment - youth unemployment is above 25 per cent. Sinkaya touched upon Iran's foreign policy in the upcoming period and said, "The elections in Iran will not affect Iran's foreign policy; especially its policy in the Middle East, as much".
Analysts have rejected Raisi's promises of jobs and cash handouts as unrealistic but admit these could win traction with voters who have felt few benefits so far from the nuclear deal.
In the 1980s he helped sentence thousands of political prisoners to death.
Speaking on May 8, Rohani said voters did not want someone who in the four decades since Iran's 1979 revolution has only known how to "execute and jail", adding that the era of extremists is over. Dozens of people were killed and hundreds arrested, human rights groups say, in the worst unrest to hit the Islamic Republic.
Mohammad Khatami, another reformist who served as Iran's president from 1997 to 2005, also has endorsed Rouhani.
Turkey's longstanding neighbor Iran is holding its breath ahead of the 12th presidential elections due to be held today, as current Iranian President Hassan Rouhani is expected to win the elections against his strongest opponent, Ebrahim Raisi.
In a tight contest, a traditionally high turnout among conservatives could be enough to give Raisi victory.
"We want freedom of the press", he declared. Authorities barred Ahmadinejad from running in Friday's election, and Khamenei days ago warned anyone fomenting unrest "will definitely be slapped in the face".
"He is an efficient manager and also because he is mindful of the weak and deprived classes of the society", another Iranian said, "a class that is being crushed under economic problems". He is a leading expert on Iran and USA foreign policy, a businessman and president of the International American Council. This palpable absence of economically left-leaning politicians from the moderate camp will remain politically relevant, and continue to rear its head in Iranian elections as a source of intermittent populist blowback.
Although Twitter is officially banned in Iran, the candidates are using it, and also the messaging app, Telegram, which has over 20 million users in Iran.
