I will watch this election with interest. But it's my understanding that no "liberals" are seriously challenging President Mahmoud Ahmadinejad's re-election.

Former Prime Minister Mir Hossein Mousavi would best be described as a political moderate, and his recent polling results show growing strength. His election may provide some breathing space for reform, and international rapprochement on the nuclear issues.

I do wish Mousavi well.
