How did we arrive to this point where a huge chunk of the population is in one reality and another huge chunk of the population is in another reality? Segregation of information sources? Politicization of media outlets? Self-reinforcing social bubbles? A combination of all of them and more?
Having a trustworthy election process might go a long way (voter ID, regular verification when doubts arise etc.). As a European I find the images from Georgia's vote counting absolutely astonishing.
Despite claims of massive voter/election fraud and massive incentive to find it, no credible law enforcement or media agency has been able to prove it at a scale that matters. Maybe a couple hundred fraudulent votes have been proven across the country.
There is just no credible evidence
