Because I think old Joe realizes the jig is up and that he's not really the president in waiting and he'll have to concede to election to Trump before this whole thing is over with.
Even Joe is not stupid enough to claim his party didn't cheat when now there is so much evidence proving election fraud.
He'll go down in history as the one who claimed victory but then had to give it up. He'll forever have an asterisk next to his name as a three time loser.
I wish I could share your optimism. I think Biden still gets inaugurated but the evidence of fraud will be so overwhelming that tens of millions of Americans will know in their hearts that he cheated.
I hope President Trump never concedes, no matter what the outcome. He owes these people nothing.
