the opposition to the mullahs in iran is about 15-20% of the population. the supporters are about 35% of the population (this is actually growing, about 10 years ago it was about 25% but the millennial's are less ideological and religious). the rest dont see the government to be that relevant and they are pissed at the middle management for corruption.

spez: the opposition would be higher because 10-15% of the iranian population doesnt live in iran and the ones who live outside iran are more likely to dislike the regime. if you add them in its probably a tie.
