I think today is election day.
The last president, Ahmedinejad has reached his term limit and cannot run again. Which the Ayatollahs are probably glad about as he had been openly in defiance to them in the recent past.
Most candidates that may disagree with the ayatollah have been removed from the running, including former president Rafsanjani and others including Ahmedinejad's preferred successor.
It will be interesting to see what happens.
