Nate Silver reacts to Iran's Guardian Council admitting there was widespread fraud:
The Interior Ministry's goal here must be one of two things. Either they're hoping to gain credibility by arguing, in essence: "Sure, there was some fraud! But there weren't 11 million votes worth of fraud!", an argument that echoes the Ayatollah's specious comments from Friday. Or, something has clicked and this is the first step in their starting to throw Ahmadinejad under the bus.
