without demagogues, spin doctors and other forms of corruption of the process..

You know, the things that convince regular people to vote against their own best interests aka for right wing and centrist frauds.

As for how to remove those destructive elements, I'm thinking publicly funded (as in zero private money allowed, not even self-funding) ranked choice elections with a shitload of mandatory independent fact checking and robust enforcement of all election laws and regulations.

Goes without saying that all laws giving one or both establishment parties an inherent advantage over the other or "third" parties would need to be scrapped too.

A whole mess of redistricting would be necessary too, of course.

I'm not saying it would be easy or even POSSIBLE to achieve, just answering your question 🤷
