Mike Huckabee launched his new radio program without a hitch yesterday -- except it appears that his first caller was actually a plant.

The American Spectator's Jeffrey Lord has unearthed the true identity of one "Mike from San Francisco," who turns out to be Mike McVay, the senior vice president of programming for Cumulus Media, which owns and operates Huckabee's new show.

"Well Governor, let me start by saying it's great to have a different opinion and a different person on the radio and I'm very, very happy that you're doing this radio show," McVay -- or "Mike from San Francisco" -- told Huckabee. "One of the reasons why I want to listen to your program every day is because you ran for office and you've been a politician, you have a different perspective I think."

Lord also notes what's not being said, but certainly implied: the "different perspective" is a reference to Rush Limbaugh.
