Rush had enormous talent but did decent conservative folks a disservice by not confronting the real issues and just being a sock puppet for whatever Conservative, Inc. cared about that day. Even after tens of millions of dollars in the bank, he could not, would not, speak to the significant & existential issues facing his listeners. He became a distraction, a balm to soothe majority white America as our children's future was murdered.
As for his replacements, they are just typical bug men of no consequence and lesser talent.
