@Merry Andrew,
Democracy Now is on NPR, at least in my area. You might like it, Merry. I do prefer Alternative Radio, but there is some overlap. Don't confuse these shows with people like Rush or Glenn. DN & AR have a variety of speakers on world issues, some I agree with, some I don't, but all tend to be interesting and insightful. As Amigo pointed out, some of the topics can get heavy, even frustrating to listen to in today's world, but always thought provoking.
