There is but one cause for concern, as Gray Falcon explains it:
You see, it looks very much like a "color revolution" scenario: the US-favored candidate contests election results, claims victory, and his supporters riot till the government caves in. But then, couldn't the incumbent actually steal the election knowing full well that he can paint the resulting opposition protests as a CIA/NED coup attempt, whether that is actually true or not?
The fact remains, however, that the technique of "democratic coup" pioneered by the Empire in Serbia - and applied elsewhere since - has made it effectively impossible to judge whether any election, anywhere, is actually legitimate.
In any case, the reports of the death of the Islamic Republic are greatly exaggerated.
