We all know how Joe Biden won the election from his basement! He defied all odds and won. If you have a mail-in ballot system it better be like Oregon (so said Obama) where the signatures are on record and can be compared to those sending in the votes to prove validity. It seems that was the difference. Paper ballots are the only way to avoid VLT fraud and make elections valid on election day.
Instead of all this so-called statistical mumbo jumbo, what really made the difference is that there were more Americans than ever before who wanted to get rid of the sitting President, so they came out in much larger numbers than usual.
Trump got more votes than any sitting President before him because his supporters turned out in record numbers to vote also. There just were not enough of them.
Every poll had Biden ahead of Trump for months prior to the election. Trump was already complaining about potential voter fraud prior to the election, but he did nothing about it. The reason is simple; he was laying the groundwork for bogus claims of voter fraud in case he lost. He would not have said a word if he had won.
It was Trump who ensured that Biden won the election.
