To be fair to the person your replying to I think that percentage you wrote is the crux of the whole thing. Quite large segments of the american population believe fraud >>0.0001% whereas other quite large segments share your view that it is ~0.0001%. And perhaps there is a segment that truly believes it is <<0.0001%.
Though I am unsure what the null hypothesis should be in this case it does seem that the probability of the reality being >>0.0001% is above zero.
Stop with the conspiracy theorizing. There are literal billions spent on elections every year, and if there was fraud being perpetuated by one of the parties, it would be in the interest of the other party to spend massive amounts of money to uncover said fraud, and they do, and they have found nothing of substance.
In addition to private study, there have been countless academic studies that state the same.
Stop giving breath to ideas that are without evidence and which are corrosive to our democracy.
Stop being obtuse, all you are doing is eroding trust for the sake of eroding trust.
It's also hilarious how much of the fraud that does happen is perpetuated by Republicans because their party tells them that Democrats commit fraud.
