:::::: The numbers are indeed possible. First is that the numbers from the 1997 election cannot be used to compare to the current one becuase this was before the point in which the youth would take on a much bigger position than they did today. the conservatives were still around and the youth could not vote then, but now the youth can vote and the conservatives have either died or changed to rather anti-Ahmadinejad. The conservative candidate was nothing like ahmadinejad so he could have had a good 8 million votes. And if you add Rezaee votes with it it comes around 9 million for the consevatives in total. 60% of iran is under 30, and they only know problems under this regime or more specifically, this administration. Besides Ahmadinejad is massively unpopular and the numbers from his previous election are going to decrease because of the increase in sanctions and further isolation from the rest of the world. YOu cannot think that his approval will go up because the nuclear program was started long before ahmadinejad, he just publicized it and his threats against Israel further promoted them, He makes useless provocations against the Holocaust, going as far enough to invite David Duke to tehran to talk about it, and this is not going to promote him very well. Next, most of the programs in Iran were started in the Khatami or even Rafsanjani administration. so the fact the claim that he is supporting the poor is dubious and the Iranians realize this because he has slowed them down or stopped them wholly, in order to pay russia or the military. And he has also placed Gas rationing on one of the largest producers of oil in the world. Point, being Ahmadinejad is not going to be quite popular, even within the conservative corners of the government. Karroubi is popular where ahmadinejad supposedly is so I dont see anything wrong with his votes and the upper class and middle class are going to vote for mousavi. Some of the lower class are going to vote for mousavi since they remember his handeling of the economy in the 80's so that will give him lots of extra votes. Rezaee is still really hated due to his running of the revolutionary guard in the 80's. And do you think that the government was going to tolerate a runoff between two reformists that each got more votes than the conservatives combined. Absolutely not in a million years. So the numbers are reasonable as mentioned above. Next is that you cannot rely on polls in Iran or whatever any government group is going to say. The polls that are "official" are made by the government. you know what I mean. and the groups (the islamic participation front) cannot know the exact extent of their popularity because the people fear evin if the open their mouths.

Second point is that i might have contradicted myself earlier. Any memo that is made by the government is going to have the seal on it, making it offical, period. It does not have any numbers in order to prevent trails as I mentioned Earlier. 
Im going to leave this on the page. The first reason is that the letter, wheather fake or not, is being widely circulated around Iran, so it is being used as a catalyst to the protests. The second is that Wikipedia is not a forum in order to determine wheather or not a document is fake or not, If the document is of encyclopedic value, as it is being actively used within the situation as it is in the protests it should be kept. wheather it is fake or not, It is evidence that is being actively used there is vote rigging, (Talk)
