In the last 2 decades, the major English bloc of US, Canada, UK and Australia has been in lock step toward the shift to the right. I think it is no coincidence that it aligns with the meteoric rise of Rupert Murdoch’s media empire. To satiate his incredible greed, his media organizations have fed into people’s fears and laid down the groundwork for today’s social media companies promoting inflammatory content to maximize engagement. I don’t know if democracy can survive without reining in popular media and significantly reducing biased and false reporting.
That is indeed a problem that needs to be resolved, and likely through ranked choice voting. But as a country, we tend to focus too much on the presidential election. Change will have to start in the congressional elections - both at federal and state levels. The issue of votes splitting will be a lesser issue in these elections except in a few large districts. That will also be where smaller fundraising campaigns would go further.
