I was listening too -- he said something along the lines of the following:
Rush Limbaugh:
"I've been thinking.... maybe I should subscribe to the New York Times and then endorse John McCain" (clearly tongue-in-cheek)
"....or I could endorse Huckabee just because he keeps winning, hanging in there" (he's been bashing Huckabee for weeks)
"...or maybe we should all rally around RON PAUL, at least he actually believes in the Bill of Rights!"
The Ron Paul one is a QUOTE, the other two very close paraphrase. While he might be warming up to Huck a bit, I'd say in the overall context it was very positive. I really don't think he was serious with the Lieberman with McCain as VP thing.....
I think Rush is a spineless windbag, but this mention of RP was positive!
