The Leveretts sum up their trip to Iran:

Conversations and observations in Tehran confirm our assessment that the Green Movement’s social base is shrinking, not growing.  We met a number of young people who claimed they had supported Mousavi’s presidential candidacy (and, in some cases, said they had participated in demonstrations against the results in the first few days after the election) but who now say they are deeply disappointed in Mousaviin particular, for having continued protesting against the outcome after failing to produce evidence of electoral fraud.

I'm not impugning their evidence; but I don't believe it is in any way indicative of the broader support for fundamental change.
