Dr. Mike Newcomb isn't content with healing the sick. He's on a mission to heal the country, if he can, one radio show at a time. Newcomb's progressive, liberal radio show On Second Thought began last summer and has quickly expanded from its initial hourlong time slot in the morning to three hours during drive time. Newcomb's a physician in the mornings, making rounds at local nursing homes and then rushing to KFNX's downtown studios for three hours of political discourse with callers that has become more lively as his listenership has grown. His theme music has evolved as well, with songs like Tears for Fears' "Sowing the Seeds of Love" getting replaced by edgier tunes like Ozzy Osbourne's "Diary of a Madman."
