The three key groups are, in order of significance, the boycotters, the reformists, and the ultraconservative Paydari party members along with other like-minded hardliners.
At least 60 percent of eligible voters refused to go to the polls, leaving the race to one pro-reform candidate and five conservatives, two of whom withdrew before election day.
Until the final hours before the election, conservative figureheads and even top IRGC officers made extensive efforts to persuade either former nuclear negotiator Saeed Jalili or Parliament Speaker Mohammad Bagher Ghalibaf to withdraw, giving the other a better chance to win in the first round. Despite their efforts, the plan did not succeed.
Now, pro-reform Masoud Pezeshkian and Jalili are off to the runoff election for the final showdown on Friday. In the meantime, the three groups have to make tough decisions to shape the country's future.
The reformists need to put an end to their hesitations and stand firm in big numbers behind Pezeshkian to ensure a victory. At the same time, Paydari and other "revolutionary" hardliners will certainly do everything to support Jalili and enable him to form his ideal non-compromising, non-conformist hardheaded revolutionary government.
