I am not surprised that someone (not hard to guess who it might be) tried something like that including to make it look like some attempt of amateurish tampering. That way it will get spread early and to the right people nevertheless and since nobody can tell between truth and lie everyone is believing that version that fits their bias most. I doubt it will have a lot of impact right now but that's also the point of the leaks happening now. Nothing creates more destabilization among enemies than confusion and that means your side will always win. If your favouritized candidate wins or if the other candidate wins doesn't matter, in case the latter happens these leaks will create enough lasting damage to spawn a new set of conspiracy theories from which it is ensured that the next election you will achieve your goal.
