Was the Iranian election rigged?

[Antonio the Sixth]

It's hard to immagine that a fraud can be enough to bring Ahmadinejad a 33-points margin if he had lost the election. It would mean an ubelievably massive and hyper-organized institutionnal fraud as in Russia or Algeria.
No, the worst of this horrible election is that a mad reactionnary was legallly re-elected after having been legally elected.
