None of the above, because I'm not a conspiracy theorist.
I would generally be more of this type of person myself. But I also know that some very marginal shenanigans go on with these types of situations. Washington governor's race was pretty blatantly obvious to people watching the recounts and court proceedings. But as the judge pointed out, "What do you want me to do the provisional's got mixed in with the regular ballots we can't reseparate them out now."
The system isn't 100% perfect, but its pretty damn close.
