My first choice would be Mark Steyn.... next Chris Plante who I listen to on WMAL in preference to Glen Beck. Plante already has a show though and Steyn doesn’t. I don’t think it makes sense to continue using the Limbaugh name - it’s unlikely any replacement host will draw the same kind of numbers.
THat's a huge problem and why Hannity is the likely talk radio guy that at least some will go to for the counter from the left.
Once again he will never replace Rush but he does has the numbers requirement to help counter the hard left.
Ben Shapiro doesn’t do a bad job on the radio. He talks a little fast but does his homework.
