Do you really need evidence to support the obvious? Do you actually believe not a single case of voter fraud happened? You literally can type into Google and find your answer.
I'm not saying it would make any difference, Biden won by a landslide, just that it's shallow minded and disingenuous to say things like no illegal votes were found, and shallow thoughtless dribble is all we get from antithesis and I'd hate to have such a dullard on my side, if I had one. The news media(minus conservative sources) likes to pretend that voter fraud never happens when the left wins but seem to imply Trump won due to collusion as if people have no free will. It's all hypocrisy and reductionism on both sides.
