Fox and the rest of the media network is the main player. They spend the energy required to present an alternative reality for their base, and have insulated their viewers from any discussion on a shared common reality. Furthermore, they are effectively part of the Republican Party. So they create and maintain a political reality which is purpose built to achieve political goals. The underlying assumption of western liberal democracies is that participants can figure things out together. You cannot figure things out when you have one side intentionally creating alternate narratives to stymie conversation and debate, to shore up negotiating power for the leaders of their bloc.
