IMO, the references to ACORN and the tightly-fought Bush-Gore 2000 election kind of take away from a very serious situation that is unfolding in Iran. It appears very likely that massive fraud was involved, violence has erupted out of frustration with what transpired, and a "reign of terror"-style repression is plausible.
With respect to the geopolitical issues concerning Iran, nothing has changed for the better. Ayatollah Khamenei remains entrenched in power and holds the key decisionmaking authority. Mahmoud Ahmadinejad remains in power and may well become even more implacable and confrontational in the wake of his "victory" (never mind how it was achieved).
