Is an Ahmadinejad victory good for Israel?

Is it better for the President of Iran to be an over-the-top religious fanatic and overt anti-Semite, than a "reformist" who is really an arch-conservative with a facade of moderation? It's tempting to say yes. But Jonathan Tobin responds that Ahmadinejad's antics have not been much of a liability to Iran, so the West is better to support division within Iran's upper ranks.
