That will never happen. When Reagan ran for president in 1980 a lot of Democrats voted for him which means at the voter level he was liked by both parties. However, the news media and the Democrat party leadership, from day 1, painted him as an evil man who always had his finger on the button to fire nukes. They said, "he shoots from the hip" (which to this day I still don't know what that means).
Biden has the lowest approval rating of every other president which means if he actually does run again and because of voter fraud becomes the nominee, he won't get enough real votes to amount to anything. Who ever the Republican is who runs against Biden (or whomever the Dems prop up) will get treated every bit as bad as they treated Trump.
