I haven’t listened to Levin enough to know, but Rush has hinted multiple times that his Trump commentary, commentary that is just shy of advocacy, is part of a bigger picture. I’d guess Rush (and likely Levin) is “in” on some behind-the-scenes strategy.
Rush has spent a couple of decades claiming to champion conservatism. He’s throwing all his credibility away by pimping for Trump, whose views on most issues are not even close to the classic conservatism Rush espouses.
I’ve stopped listening to Rush and Levin. I don’t believe or trust what they say any longer. They’ve officially joined the ranks of the blowhard brigade.
