In general when lesser known political figures go up against more widely known ones, the former tend to lose, unless there is a specific reason why the more well known candidates should be widely unpopular or disliked. But even then i would still say that just being more of a household name is often enough to overcome a negative image.

In this election it appears that there will be a fair number of candidates whose names are, as far as i understand, widely known in Iranian society, and that makes it exceedingly difficult for a random MP who has not particularly distinguished herself in the media or held major government posts to win.

Then again, as i always stress when i talk about a country whose politics i am not familiar with, i could very well be wrong and someone with more firsthand knowledge of the situation is more than welcome to correct me.
