Iranian President Hassan Rouhani's visit to a coal mine in the north-eastern province of Golestan will remain a memorable event in Iran's 2017 presidential campaign.
Mr Rouhani has faced a significant challenge from conservatives because the landmark nuclear deal with world powers that he negotiated in 2015 has not triggered the economic recovery he predicted. He has gained the image of being a conservative mover and shaker whose motto is "Can't be done?"
Raisi's team had reportedly told Ghalibaf's entourage that they would appoint him as first vice president if the conservative cleric is elected president.
On May 16, Tehran Mayor Mohammad Baqer Qalibaf dropped out of the election to back Raisi, believed to be a favorite of Supreme Leader Ayatollah Ali Khamenei. All candidates must be vetted by a hardline body. Rouhani, 68, is also a Shi'ite cleric. "I think that the new French President who was previously the minister of economy will continue this path for expansion of constructive relations with Iran".
Mr Raisi, is now the head of the powerful Imam Reza shrine and charitable foundation in the holy city of Mashhad and, in addition to attracting support from traditional conservatives, is seen as the favoured candidate of the security establishment.
"If Raisi wins, two things will happen", Abrams wrote.

"We should make a fundamental decision to create unity in the revolution's front and I call upon all my supporters across the country to come out in support of my esteemed brother Hujjat al-Islam Ebrahim Raisi and make him succeed in forming the government of work and dignity". Rouhani was the former secretary of the Supreme National Security Council (SNSC) from 1989 to 2005. Rouhani's win in 2013 was a surprise landslide in the first round, but disappointment with his economic and social achievements and a low turnout might necessitate a second round.
Emmanuel Macron, 39, who is a former investment banker and economy minister, won the presidential election with 66 percent of the votes on May 7.
Opposition and reformist figures are backing Rouhani.
Some conservatives had been unhappy that Qalibaf was standing again and risking a split in the anti-Rouhani vote.
Rouhani's recent fiery campaign speeches have led to a surge of public interest.
That has left a vacuum for many working-class voters who fondly recall the construction boom, cash hand-outs and earthy rhetoric of Ahmadinejad's rule. "As long as Khamenei runs policy, nothing will change", said art student Raika Mostashari in Tehran. Draped in a black chador, the full-length dress favored by observant women, Jamali said that Raisi is the only candidate who can confront the corruption that has spread through the country, that he is an honest man. If Raisi takes power, the future of the nuclear deal and peace in West Asia could be at stake.
Although the agreement lifted worldwide sanctions, the United States continues to impose unilateral measures that have scared off investors.
Raisi's human rights record has troubled many. On the one hand there's Rouhani who is trying to convince voters and reassure the worldwide community that the continuation of moderate government in Iran for the next four years will result in more integration of Iran in the global system and improve Iran's economy.
Polls expected to open at 03:30 GMT and close at 13:30 GMT, which can be extended.
