I’d add to the Radio list, Dennis Prager. He was not a Trump original BUT since the end of the primaries, he has been VERY FIRM for Trump.
I’ll add to the radio list: Jim Quinn and Jeff Kuhner.
Dennis Prager made the best arguments for voting for Trump tailored directly to the #nevertrump crowd, coming from someone who was opposed to Trump in the primary.
Mike Gallagher was another radio guy who was exactly as firm for Trump as Hannity and Ingraham.
