Well @Weird Tolkienish Figure, Your GOP has done such a remarkable job, just keep going.
Sure, Einstein.*
With that attitude, nobody would find his way to Carnegie Hall!
Goebbels pointed out that one theory of propaganda (the "English" one) was that repeating a lie gets it believed. How could that be true if repetition didn't yield different results?
Or how about the butterfly effect, where a small change in initial conditions of a deterministic nonlinear system can result in a large change at a later state. So if you are operating in such a system, your input may be identically repeated, but a small difference in the system parameters can yield very different results.
In other words, it's not necessarily insane to be persistent. The Dems have successfully advanced agendum after agendum via incrementalism. Sure, it's more difficult to enact retrograde (reactionary) incrementalism, but abandoning it for hopes of miracle "resets" is very risky. Maybe we're at the point where there's no hope for America but a "Hail Mary," but I don't think so.
*Yes, I recognize the quote is actually from Narcotics Anonymous, not Albert Einstein, but it just really irritates me.
