That statement is very telling to me. You are saying you don't question his conservatism. You don't claim he elaborates it explicitly. From his constant attacks on Democrats, I think people on the left and the right ASSUME his conservatism. They may be right. I am not trying to attack Limbaugh, I am just trying to parse what he actually says. He seems to avoid talking about social issues, and he seems to let people fill in the gray areas of his beliefs, but only talking in certain areas.
I get what you are saying.
