I often listen to political talk shows on my car's satellite radio. When I get fed up with a right wing show I switch to a left wing show, when I get fed up with that I look for another right show, or give up. One thing I notice is the sort of ads that go with the shows. While some are probably for worthwhile products, a lot are get rich quick schemes, instructions on how to get credit by incorporating in Nevada, and the like.
What is interesting is that, so far as I can tell, the same ads run on left wing and right wing shows. That suggests that many of the people who listen to such shows, left and right, have something in common.
