Elections, as we argue in 2301, are devices which among other things connect the general population with the law, thereby lending it legitimacy. But if an election seems to have been fraudulent, the opposite can occur. This is especially true if the fraud seems obvious, and a large percentage of the population agrees. The governing system then loses legitimacy, society crumbles and either government does something to reestablish legitimacy or removes the pretense and just clamps down on the population.
This may help explain the results of the recent election in Iran. Its president was reelected by a comfortable margin, a result which seems improbable based on popular opinion. Fraud is widely suspected. Protests have erupted, and some suspect a coup is in the works.
