@reasoning logic,
As I have already said, I think that would depend upon other factors besides the listening to npr. I think it depends upon your foundational or core beliefs, as well as how naive you might be. I am not saying you are, you may not be, I am merely pointing out that some people are more influenced due to their own lack of convictions or core beliefs. I can listen to npr and not be influenced much, and after a while I merely give up on it as a waste of time and wish our tax dollars did not support the crap. Look, I am also not going to say everything they say is wrong or biased, but on balance I believe they bring a liberal bias to the stuff they discuss.
In fact, I think it is a bit naive to believe that there is any journalist or news item that is unbiased. Everybody has basic beliefs and biases, which they will bring to the table in the course of discussing an issue. The reason I favor conservative talk shows is because I am more likely to hear opinions that make more sense and are more logical in my opinion. For example, I believe Limbaugh is popular because he voices what his listeners believed already, before they started listening to him. Many people, including me, have been fed up with biased news for a very long time, and so it is refreshing to hear opinions that agree with us. The libs have it bass ackwards in regard to folks like Hannity and Limbaugh, most of their listeners do not listen because they have been swayed by their rhetoric, they listen because they have finally found people that agree with them and are reporting what they would consider more accuracy and truth about issues.
I think the reason conservative talk has boomed like it has, is because conservatism resonates with more people, because people are basically more conservative whether they vote that way or not. Example, I have a good friend that voted for Obama, but he is actually fairly conservative, we share many of the same values, but he fails to see that Obama is doing the exact opposite of what he thought he should do. Meanwhile, he hates Limbaugh, but he doesn't know what Limbaugh says on issues, and he actually agrees with Limbaugh but doesn't know it. I think it is a personality issue, where Limbaugh's ego comes across too strong for him. Most people live their lives in a conservative way to be successful. Also, conservatives enjoy listening to reason and logic. In contrast, liberals believe and behave due to emotions. For example, a liberal will endorse government programs if they are intended to supposedly help somebody, never mind the fact that the program does not work and might actually create more problems than it solved. Example the Great Society.
