Whomod: You ask why Rush Limbaugh is considered an authority over the likes of Martin Sheen. Why not? Is there any reason on Earth to pay any attention to some third-rate actor on politics? The Hollyweird types seem to think that playing President on TV makes someone a political expert. Bzzt, wrong!
And before you point out that I didn't give you a reason to listen to Rush, that wasn't my intent. I merely point out that your examples aren't worth listening to either.
