It will NEVER be proven that Beijing Biden won in a free and fair election. This is because winning and stealing are not the same thing. Trump will forever be the only candidate who actually "won" the most votes from actual voters, while Beijing will remain the one who "received" the most votes from virtual voters, algorithms, and fake ballots. Beijing will NEVER be known as a winner.
You got it backwards. Biden won 7 million more actual legal votes. Trump lied about election fraud and caused an attack on the Capitol and completely destroyed faith in free and fair elections by Trump supporters who believed every lie he told.
