You’re correct. The fraudulent election is old news and no longer serves our purpose. Not clear on what your argument is.
President Trump made major inroads into the minority vote. The only way Biden could've made up the difference is with the white vote.
It's kind of like the Russia collusion thing. President Dr. Trump went around saying, "There was no collusion. There was no collusion", when, in fact, there WAS collusion. It was perpetrated by Hillary Clinton in the form of the fake Steele dossier.
He made the occasional reference to the fake dossier but he never really hammered it home.
