Some reports are coming in of a softening in tone in a speech from the Supreme Leader. The full speech is not yet translated but here's the money quote filtering out:
"It is natural that when some people's favorite candidate fails to receive enough votes they become emotional and express anger, that does NOT make them anarchists. All the candidates are within the family of the regime and this has nothing to do with the foreigners."
Waiting for confirmation, but it sounds like a retreat to me.
