Yep, Boortz is not TRN. Still seems a bit shaky - Boortz isn't a huge player in most markets to cause much harm, but he's still a talk show host, and sometimes competitor, not just an author. If I was the fifth-string station running Humphries, Mike Reagan, et al, I'd be pi**ed to have them interviewing Savage or the like who's likely on a better station in the market. IIRC, Tammy Bruce filled in for Jerry Doyle not long ago... yikes!
However, The High School Dropout running TRN didn't get the advanced math courses he needs to figure out these difficult calculations, hence, he can't determine whether he can afford to pay talent to fill in.
