What do we actually know about Mousavi? Is there evidence that he would change Iran from a thugocracy to a democracy? I have a feeling that Dinnerjacket did win the election by a narrow margin. Quite why they thought they needed to fiddle the results is open to speculation.

As far as Obama giving support to one side over the other I think it would be counterproductive. This country has had over thirty years of indoctrination that the US is the Great Satan. I think any interference would be misconstrued and seized upon by the mad mullahs as evidence that the US wants to take over Iran and put a puppet in place.
