Laura Secor has a must-read:
There can be no question that the June 12, 2009 Iranian presidential election was stolen. Dissident employees of the Interior Ministry, which is under the control of President Ahmadinejad and is responsible for the mechanics of the polling and counting of votes, have reportedly issued an open letter saying as much. Government polls (one conducted by the Revolutionary Guards, the other by the state broadcasting company) that were leaked to the campaigns allegedly showed ten- to twenty-point leads for Mousavi a week before the election; earlier polls had them neck and neck, with Mousavi leading by one per cent, and Karroubi just behind.
Historically, low turnout has always favored conservatives in Iranian elections, while high turnout favors reformers. That’s because Iran’s most reliable voters are those who believe in the system; those who are critical tend to be reluctant to participate. For this reason, in the last three elections, sixty-five per cent of voters have come from traditional, rural villages, which house just thirty-five per cent of the populace. If the current figures are to be believed, urban Iranians who voted for the reformist ex-president Mohammad Khatami in 1997 and 2001 have defected to Ahmadinejad in droves.
