From a November poll of Iran public opinion by World Public Opinion:
As compared to others, Mousavi supporters are far more likely to say that the election was not free and fair, that they do not have confidence in the election results and that the Ahmadinejad is not the legitimate president of Iran. However a modest majority of Mousavi supporters says the opposite.
Larison pounces:
The detail that even a majority of admitted Mousavi supporters does not endorse the key claims of the Green movement is remarkable, and so it will probably be dismissed out of hand by pro-Green enthusiasts. If that figure is correct, however, it makes the breadth and depth of the Green movement’s support even more questionable. It would mean that most of the people who are willing to identify themselves as supporters of the leading opposition figure do not accept even the most basic critiques of the election and Ahmadinejad that were at the heart of the movement that claims to represent them.
