This is pretty funny. The conservative Media Research Center has posted a public letter urging supporters not to listen to non-conservative media.

Exposure to diverging views: no telling where that might lead. The risk is high and real that listeners may well find the New York Times more credible than Fox News.

But that's not the funny part. The funny part is that MRC is announcing with pride that their letter urging conservatives to forswear non-conservative sources of information has been signed by Rush Limbaugh and Mark Levin. Of course it has! If you're selling high-fructose soda, you hate to see your customers wasting stomach space on milk and orange juice. The real question though is: will Limbaugh and Levin stop reading the Times? It's not like they do any reporting themselves. Somebody has to tell them what's going on in the world, and I don't think either of them is such a fool as to rely on World Net Daily.
