Yes, I haven't listened to that one precisely because it deals with Trump, on which subject I find Mr Harris fearfully po-faced.
I believe his antipathy isn not party-political. However, the impression I get is that his objection is quasi-aesthetic. - that he finds the mere idea of Trump offensive to his middle-class, liberal intellectual sensibilities. He doesn't seem to grasp that offending people like him on those grounds is precisely the point of Donald Trump.
