Liberalism
5
To respond to Louiethe20th, conservatives are the primary consumers of television news. More conservatives watch not only Fox, but also MSNBC, and CNN, than liberals. Liberals have routinely identified their primary source of news as newspapers. You can draw your own conclusions about the cause and effect, but the fact is that 48 percent of the population voted for somebody who identified himself openly as a liberal, and 50 percent voted for someone who was pegged as a liberal in 2000 (though he didn't admit being one). That is the test of a political ideology, not consumption of infotainment.
When liberals turn on the radio, they usually turn it on for music. When they watch TV (and according to the available, they don't watch as much TV as the rest of the country), they watch movies. Liberals aren't generally in the market for blather and gossip, whether they agree with it or not. Hence Air America's difficulties. We'd much rather listen to an interview by Terry Gross, or Prairie Home Companion. Unfortunately, we'll never know how well NPR does because Arbitron refuses to rate non-commercial stations.
