Yes, James Golden has been Snerdley about 20 years but the name Snerdley has ties to Rush even back into the 1970's in his local radio days. Rush spoke of the Snerdley tradition once many years ago I recall.
I also pulled this from the Wiki so take it for what its worth but it sounds accurate. Rush's WIXZ job would be from the early 1970's so Snerdley may have been a made-up name even from as far back as his childhood?
Snerdley is a pseudonym Limbaugh invented many years earlier when he was a disc jockey on WIXZ (when Limbaugh went by the name Jeff Christy); he would use the name Snerdley for supposed-listeners who would write or call in, usually professing to be big fans and part of the "Christy Nation". More recently, the name Snerdley has been used for his call screeners, both male and female.
