Build a new model?

“You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.” — Buckminister Fuller

But taken to extremes, such thinking would lead to frequent divorce, destruction, and abandonment of institutions and plans.   Sometimes you do need to fix what’s broken instead of replacing it with something brand new.

There comes a point, though, where replacement is the best approach. Has the Democratic Party reached that point? I don’t think so.
