Ahmadinejad stands a good chance of winning the elections, which would be perfect.
If a fake moderate like Mousawi wins, he will continue the nuclear program, but it would take the world years to build up hostility toward him comparable to what is felt toward Ahmadinejad. In the meantime, there will be no sanctions. Relatively soft-spoken Mousawi won’t antagonize the Westerners like Ahmadinejad did, and the fragile consensus against Iranian nukes will dissolve.
