Sistani and Iran

According to Juan Cole, Iranian reformists have reached out to Grand Ayatollah Ali Sistani to intervene in the Iranian election crisis. Sistani is the highest-ranking religious scholar, not just for Iraq, but for all Twelver Shi'ites, and if he chooses could provide a key rallying point for Iranian disaffected with the regime. Granted, Sistani is a bit busy at the moment, but Cole's right, this could get really interesting.
