Rush Limbaugh is a blow-hole, a douche nozzle, a dick. There isn't much that could be said that would be an adequate insult, and the irony is, you probably--as a liberal--couldn't get under his skin no matter what you said. But Rush took a phone call from a seemingly sincere, conservative military veteran. And said veteran smacked Rush down but good.
It's difficult to understand why Rush didn't silence the call. But once he finally came back to zing the guy, his retort was pretty lame--and very defensive. He ends up insulting a whole category of Republicans as traitors to the cause. Who, you ask? Apparently anybody who voted for John McCain. . .which is a lot of Republicans. So who does that leave for Rush?
