I don’t know - I would be willing to bet the conversation would be very civil.
Rush is NOT given to anger toward liberals - when engaging them in person.
He really can “leave it at the office”.
That’s his gift - he likes and respects people.
The show is the show - in person - he engages with people.
Rush is personal friends with a lot of liberals and just about everyone who has ever met him (with the obvious exception of the women he’s assaulted) talks about how friendly BJ is.
Rush has dedicated his life to conservatism, it’s not just a show.
