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.
Bidens win was attested to by recounts until they became ridiculous. It was also proven by 60 court cases. The fact is that Bidens victory was flat out proven. It has nothing to do with the election. The problem is you. By any measure, Biden won the election. It is known.
