I think there's something to be said for not impeaching Biden, as much he definitely should be. The Senate would never convict anyway, but impeaching him gives the democrats an excuse to replace him, although I'm not sure they would do that. He's their problem going into an election year, maybe it's best to keep it that way? It doesn't seem like impeaching Biden is part of the overall 'Plan,' especially going into an election year in which things should get really spicy.
