Sometimes I do. A few minutes of the local news on my way into work is a good way to stay current. And then there's late night "Coast to Coast AM". Sometimes I catch a half hour or an hour of that before I go to sleep.
If I'm on the road late at night for some reason, you can't beat Coast to Coast AM. Not all of the topics interest me, but many of them really make you think. Other than that I occasionally listen to AM radio for sports or news, but I really prefer television when it comes to that.
