This poll comes from here. There are fifteen days left until election day in Iran, and Mousavi is turning out some huge crowds, such as a crowd of 30,000 in Tabriz. This has not gone unnoticed by Rezaei who turned his fire on Mousavi for the first time today instead of Ahmadinejad, whom he had been hammering daily until today.
I've gathered together a few dozen pictures (okay, grainy screenshots) from the rallies here and I'm just about to run out the door so don't have time to put them all up here, but here are the best ones showing his supporters all decked out in green.
...Edit: sorry, can't seem to post the images here since they're hosted by Blogspot.
The poll doesn't really mean all that much though since turnout is going to be what decides this election. Because of this we here on the internet might even be able to help a bit by joining groups like this one and this one on Facebook, and finding people with Twitter accounts that support Mousavi that we could agree to retweet certain links of (written in Persian). This one for example.
So how about gathering together a list of Twitter users that support Mousavi and hopefully write in both English (to make the content easier for us to confirm) and Persian (since that's the only language that will have a real effect)?
