Fox does not have the bench strength to replace TC. In the science of ratings, ususally one superstar props up the rest by inertia of not changing the remote.
Waters? Nope, maybe in 5-10 years
Hannity?- Network's joke, not hardly
Ingraham? Too dry and boring.
Fox could really toss the dice and install Gutfeld and that format, but I don't think that is in wheelhouse of the 7/8 pm time slot.
Really loooking forward to seeing where he lands. I hope it is NewsMax, because I think they have the widest TV viewership.
