Tebaldi thinks that the significance of Fox News and Murdoch turning their back on Trump "is really a question of how much
Fox and others are still relevant to Trumpism," she said.
"While they boosted awareness for him pre-2016, now Trump has become such a figure in alternative media discourses that I'm not sure Fox pulling support will change much—it may just make him look still more like the outsider he pretends to be," Tebaldi added.
Trump appears to have lost the support of major conservative media that backed his rise in 2016.
