You are, of course, right.
I've long said that Rush is doing the right thing for the most people. If he went into more stuff, it would be too easy to paint him as a kook. He can do an excellent job with the basics and bring people into the bright light of conservatism. As people seek more info there are plenty of others to provide that info and although sometimes I'd like to hear more from him, I understand his limits are pretty well placed.
Well, I don't think Rush would go there anyway myself...I don't believe he wants to take issue with or go into detail regarding things like the Council on Foreign Relations and their involvement.
My feeling is that that particular story and why it is, and how it came about, leads to the root of what the liberal/marxist/statist/global governance crew are trying to do to our nation.
I touch on that type of thing pretty strongly in the series through the manipulations of David Krenshaw and his involvement in the story's "Council on International Relations".
