It's like putting an elephant in a suit and calling it a businessman. It doesn't quite work... Ok, I'm not sure where I was going with that....
Anyway, it is widely known that the Afghani elections were rigged. In many districts, more votes were cast than there are people. As for the 40% were women comment, it's just propaganda. 3rd parties have estimated it as closer to 10%.
Afghanistan is absolutely nothing like the US. In fact, it is just barely one country. The regions of it are so bitterly separated, that any federal government cannot succeed. It is a country run by regional warlords. Any "President" would only have power over the capital city and its neighboring regions. It is possible that he could form alliances with various warlords, but that does not make it much of a democracy...
