There is an unconfirmed report that the protest today was not just a couple hundred thousand, but over a million Iranians strong. Not just students, but middle aged, families, old, rich, poor, city fols, country folks, reformers and mullahs. There have even been 3 major Ayatollahs that have spoken out against not only the rigged vote, but the whole ligitimacy of the Iranian governmenrt as it is now.
And the protests on Satuday are expected to be even bigger, and held in many more cities as well.
The Mullahs might be getting concerned.
