My strongest reason to doubt the election came as soon as Khamenei endorsed the election so early and without any hesitation. That was quite unprecedented. Normally he would have waited a couple of days until dusts settled. It was so obvious that something was in the making and so obvious that they did not even count the votes.
All the doubts were confirmed so strongly when AN got that cold welcome by his supporters in Tehran and far colder one in Mashad, where the counts were saying so much otherwise.
I am sure he is not even popular in villages. Wait until he goes to a village and is welcomed by shoes, stones etc. Not only AN but K.R. is unpopular these days. They are running with an iron fist now. Otherwise, they would have shown their million supporters in no time with no hesitation. They are not even able to buy the numbers with CHELOKABAAB and a ride to a place to make a show anymore, at least for now!
