As in here , the American people believe election was rigged for Biden. They saw all the lies told on Trump. They saw him as being picked on. We know Trump got 80 million actual votes and Biden only got 50 million and the rest were fictional votes created by Democrats. They were made up, some were illegals allowed to vote. Mostly John Doe's.
