Opinion: Fixing the election was unneccessary and has backfired. At best a reformist leader could only lean Iran in a direction, not actually make a change of course. In Iranian terms Moussavi may be such a reformer even if he is still fiercely right-wing in our eyes; the failure to elect him must mean something though.

Two possibilities occur to me:

1. The Supreme Leader is weak, or losing grip of his mental faculties. In such a situation Dinnerjacket may have more power than we might otherwise expect.

2. The Regime was already scared, they know the young don't back the revolution and they are trying to maintain control.
