The problem is: There can be no more "incontrovertible evidence". With the rise of alternative facts, all evidence is now tainted by politicization. Thank you Trump. After all, Trump was caught with audio tape on the phone with Zelensky, trying to get him to investigate Biden's son, and then holding up aid, and that wasn't enough "incontrovertible evidence" for GOP Senators to throw him out. So, if you think there will ever be enough "incontrovertible evidence" of voting fraud to overthrow the election, you are dreaming.
That's how you know the alt left has lost it. When a Presidential election makes them want to leave the United States if they lost. lol. I would feel bad for the alt left but they brought this on themselves. Good news is, with Biden president, everything that goes wrong, he'll get the blame for! Just like what's happening to Trump. I look forward to passing that buck!
