The show had become synonymous with the host, so even retaining it on WHYY would be a tall order. Not impossible, sure, but understandable they chose not to go that route.
But no, there are greater odds I’ll grow my long-gone hair back by tomorrow than a show like that ever, ever ending up on a commercial talk station. I’m no fan of what they do there, but it’s just silly to think WPHT would remotely consider such a thing. Or that it would work.
