OPINION - Joe Biden has presented Democrats with a big lie of his own

The ridiculous claim that Donald Trump won the 2020 US presidential election was the first big lie to infect its politics. Now Joe Biden has presented Democrats with a big lie of his own. Will his party swallow the whopper that he is fit to be president for the next four-and-a-half years? If yes, why on earth would voters go along with this charade?
