Any thing is possible with all the outlandish bullshit trumptards make up.
Trump did say in one interview that his "pollsters" told him he needed a certain amount of votes to win. It was more than 2016. It is plausible that a person in power and $$$ could conspire to "manufacture" a certain amount of votes. It would be harder for Biden to do it, less power and $.
Trump was also desperate to stay president because he knew he would be protected from prosecution like he was during his first 4 years.
