The Washington Note's Steve Clemons has a fascinating piece today about what is happening behind the scenes in Iran. Keep in mind that "reformer" is a relative term and that all the candidates have much more in common than not:

Last night in London after appearing on Keith Olbermann's show, I got an email from a well-connected Iranian who knows many of the power figures in the Tehran political order asking to meet me. I told him that the only place possible was Paddington on the way to Heathrow -- and there we met.

He conveyed to me things that were mostly obvious -- Iran is now a tinderbox. The right is tenaciously consolidating its control over the state and refuses to yield. There is a split among the mullahs and significant dismay with Supreme Leader Ali Khamenei. A gaping hole has been ripped open in Iranian society, exposing the contradictions of the regime and everyone now sees that the democracy that they believed that they had in Iranian form is a "charade."

Dude, believe me. I relate!

But the scariest point he made to me that I had not heard anywhere else is that this "coup by the right wing" has created pressures that cannot be solved or patted down by the normal institutional arrangements Iran has constructed. The Guardian Council and other power nodes of government can't deal with the current crisis and can't deal with the fact that a civil war has now broken out among Iran's revolutionaries.

My contact predicted serious violence at the highest levels. He said that Ahmadinejad is now genuinely scared of Iranian society and of Mousavi and Rafsanjani. The level of tension between them has gone beyond civil limits -- and my contact said that Ahmadinejad will try to have them imprisoned and killed.
