If fox viewers are there to avoid the drooling, slavish, bootlicking of the liberal establishment that you see in the MSM, rather than being some dude’s fanboy, then, yes, I expect Fox News to retain the vast majority of their viewers.
Fox doesn’t have many conservatives left on there at all to listen to. Run down the list of radio hosts and you can find more than enough to listen to on any given day that are far more conservative than anyone on Fox. The only people still giving Fox an audience will be people who are not savvy enough to search out content that requires more than clicking the remote control.
