Yes. Support for Ahmadinejad was strangely consistent across the country, a real change from previous elections, when candidates drew different levels of support in different regions.
There were several other puzzlers in the results:
According to official figures, Ahmadinejad handily beat Mousavi in Mousavi's hometown of Tabriz a shocking result, given the candidate's popularity in his own region.
Ahmadinejad beat Mousavi in the big cities, even though Iran's very limited polling and anecdotal evidence indicate that Mousavi is far more popular than the President in cities.
The official figures put support for the other main reformist candidate, Mehdi Karoubi, at below 1%. That is far less than what was expected, and a drastic departure from the pattern in previous elections.
