Do you mean Jan Michelson on WHO Radio?
I don’t know the name, I just recall both an article (I think on Politico, though it could have been a post at someplace like Powerline or Hugh Hewitt) and some discussion here by folks from Iowa at the time of the straw poll about the local talk show guy really pushing Huckabee and that being a big reason for his surprisingly high number of votes in that straw poll. I’d have to go back and try to search for those threads to find it.
