To keep Mark off plugging his book, not to get his own show!
When Jon Voight wa on Beck, he said without warning, “Mark Levin’s book is wonderful” (or something like that) and Beck says quietly, “yeah, i heard”.
Clearly, his book doesn’t need plugging, but that’s not the point.
I saw the Jon Voight on Beck comment, that wasn’t anything nasty and did Mark have Glenn on to discuss HIS book? Of course not, so what made Mark think Glenn would have him on his show and I imagine Mark never had BOR on for any of his books, either and vis-versa... if that is what Mark is teed off over it only goes to make him look even more petty...
