FToI poll on the ninth presidential election in Iran has been open for two weeks, collecting about 135 responses. Taking out the non-Iranian visitors, 42% chose I won't vote whereas 40% chose Moeen. (These numbers are 45% and 42% if we substract further 6 visitors who chose the conservative candidates.) About 9% of the Iranian visitors selected Rafsanjani.
Given the audience of this web site, I think only, if any, the choices of Moeen, Rafsanjani and I don't vote can be of some meaning for the actual election.
I think it is reasonable to think of those who won't vote, as those among reformist voters who will be abstaining from voting on Friday for social reasons. Taking the reformist voters to be around 60% of the electorate based on previous elections, one gets 25% for the "boycott." Add to that the 20% that usually don't vote for personal reasons, and you get a turnout of 55% on Friday.
How many votes would Moeen get? 40% of the reformist votes, that is about 25% of the electorate — a maximum of 40% of the votes cast on Friday.
I think the remaining 20% of the reformist votes, or 12% of the electorate, will be split between Rafsanjani and Karrubi. Rafsanjani will also gain some of the conservative votes, a total of 20% of the electorate. My estimate for Rafsanjani's votes is then a maximum of 30% of the turnout.
The remaining three conservative candidates will share the rest of the votes cast on Friday, capped at 30% of the turnout.
Moeen and Rafsanjani will go for a run-off.
UPDATE: It seems the tide is turning in FToI poll to Moeen against I won't vote. News pieces suggest this may be a reflection of reality as well. We'll see.
