You could have put Alfred E ing Neuman in there and the left would have gone just as bat over him as they did her. It's a "fill in the blank" loyalty to the party, and whomever the DNC pushes to the front (by ing over other candidates) the left will kowtow to and feel righteous in the process.
All that can be said about it, now, is that 3 supreme court justices will have been planted before Trump gets ousted, and those three justices will do more harm for the ideals of the left than the last 5 GOP presidents combined and there's nothing Biden or anyone else not in the court can do about it other than continue to challenge it with new laws.
