What's Rush doing? Doesn't he read FreeRepublic? According to the evolutionists on this forum he's now officially an uneducated idiot.
He's a former sports commentator who runs a radio show. He's good at that, mostly. I wouldn't assume he knows much about the chemistry of the stratosphere, any more than I'd expect him to know how to unclog my drains. Having a radio talk show doesn't make you an expert on everything you've ever read about.
