Has Rush mentioned this on his show? If he does, it will get the story out in a big way. I personally haven't heard it on any of the talk shows, TV or Radio, to any extent.
Since Rush did not talk about it the week after it happened, he won't talk about it. I don't think Hannity has either, although I am unable to give him 3 hrs. a day, it's all he asks.
Rush has lots of irons in the fire, and I don't think he likes to plug "blogoshpere" news. The blogs are blowing by Rush, making him look lazy and uninformed.
