Partly, it’s that a bunch of people jumped into Rush’s time slot — and a couple who were already there got a higher profile. (Prager, for instance.)
Once Rush was out of the picture, Bongino jumped in, then Clay and Buck, Rob Carson, and others. So even if there were a “new Rush Limbaugh,” he would have a much harder time accumulating a Rush-sized audience.
I love Charlie Kirk, but don’t listen like I did a rush. Here in AZ we have the conservative circus with James T Harris and he is awesome. A conservative black man who tells it like it is and gets good local people to come on the show and share important news that we never hear on tv.
