To be fair to K00nah, I think he does somewhat play a "role" on the radio (principally that of a drama queen), but most of the right-wing alex-jones lunatics tend to be his callers, not him. He's just an outlet for the crazies. Then again, most of the crazies tend to be before 8:20am, which explains a great deal, since institutes tend to give meds about 8am, so it'll take 20 minutes or so for the thorazine to kick in. Perhaps he encourages the crazies a little, but isn't that what you're supposed to do for ratings? Appeal to your audience?
The drama queen thing is what turns me off, but truthfully I find most of his political commentary to be well thought out and presented, although no doubt some people would disagree with his conclusions.
If you search for the Edmund Burke Institute on the internet wayback machine you'll find some of his past writings. Of course, we have to assume those opinions are likewise his "real" views. However, you have to also consider aspects of his personal life he discusses on the air, such as his adoption of two children. His actions in his personal life would tend to support what he espouses on the air, in terms of his morality and religious convictions.
I am not really sure what "establishment republican" is. I tend to vote party-line republican but that's because they (mostly) tend to represent the views of myself and my family more than, say, the AOC-crazies. Paul Feeney, my state senator, is a decent guy even though I disagree with many of his political positions. I blanked Baker on the last ballot, even if I held my nose I couldn't bring myself to vote for him.
I've never met Kuhner, although I live in his neck of the woods. I suspect he's a pretty normal guy in person, someone you could sit around and have a beer with (as long as you do not discuss politics if you're on the other side of the aisle).
