"Although widespread allegations of fraud, manipulation, intimidation and other all too common elections tactics have been be common, statistically detecting fraud or manipulation is a challenge. For example, while mathematicians have been evaluating vote returns for irregularities in normal situational random number distribution , determining what the "correct" results should be is very difficult. However, given the absolutely bizarre figures that have been given for several provinces, given qualitative knowledge - for example, that Mahdi Karroubi earned almost negligible vote totals in his native Lorestan and neighboring Khuzestan, which he won in 2005 with 55.5% and 36.7% respectively - there is room for a much closer look." - Jason Chen from Bookmarklet
