I can't remember where I read it, but political dispositions are more nature than nurture. It makes sense too from a species design perspective: if you want coordination systems to be adaptive, you need strategies to compete, because any mono-system will have failure modes. Assuming political dispositions are natural also gives me more empathy for people with whom I disagree politically, ie so long as we are at least intending well, and even if it contributes to some ruin, we're all playing our part to keep things dynamic. It sucks to disagree and for bad ideas to win temporarily, but the alternative imo is like a car without brakes or a steering wheel.
