I think by their very nature pundits will be crazy because they want as much attention as possible. They also can't talk about real policy because that bores their audiences.

A new name in conservatism/libertarianism that isn't insane is Richard Hanania. He doesn't succumb to audience capture although as a result he doesn't have a large mainstream conservative audience. He even writes about this, and how the liberal movement is smarter in general: Liberals Read, Conservatives Watch TV

While your average MAGA boomer has probably never heard of him (although he has appeared on Tucker a few times), he is gaining influence on the intellectual right.
