The problem is Biden is too cowardly to play hardball with the Repubs, and even if he wasn't, he has no interest in changing the status quo. He's not going to run for re-election anyway and will probably hand over the reins to Harris either before his term ends or set her up to get the nomination in four years.
I'd say Pres Biden can not allow power to change hands ever again since any new WH winner can eliminate the government through force. We can't risk that so a Constitutional Convention must be called into order and this $hithole nation declared under an Emergency Declaration until the risk is over.
