Even knowing that the results of a repeat election are likely to be the same, I can easily imagine someone being petty and "losing" their key to sabotage the process as a demonstration of power. It's just human nature at it's worst.
This is casting accusation as a member of a community, without a shred of a proof.
This is also not realistic and Occam's razor applies here strongly: why sabotage your career and frankly embarrass yourself just to make a tiny election delay, based on uncertain assumptions? This doesn't pass the sniff test.
In short, I think always assuming the worst in people is not healthy and we should trust that this was indeed a honest, unfortunate mistake. This could happen to everyone.
I'm sorry. I should have made it clear that I wasn't discussing the present situation of which I know nothing about and have no reason to doubt the good faith of all involved.
I was merely expanding on the hypothetical case where bad politics overcame a theoretically sound selection process.
