I'm SO surprised more people don't know about this... I'm always dismissed when I say the elections are rigged.

I once made a list of various issues raised in various elections in various countries. The instances describe a whole spectrum of cheating. The only consistent factor is that no one believes there was cheating. The funniest was an order to change punchcards that made the holes not line up. People still found room to not see a problem with it.
