I mean I’m not going to disagree that a blanket all old must go all young must stay approach. Obviously trading Bernie Sanders for Rick Santorum would not be a good move.

That being said what does need to be dealt with is incumbancy bias as a whole. IE no matter how shitty they’ve been, the effect is over and over again keep the same guy regardless of how good or bad he is until he chooses to retire or drops dead.

The approach should be “replace the people who haven’t been looking out for their people”.
