West Valley City Mayor Mike Winder wrote a glowing testimonial to EnergySolutions this week, part of a series of advertorials the radioactive waste disposal firm is running in local newspapers. He said he thinks the company provides a valuable service to the nation, and gets a bum rap in return. As a result of this misguided missive, Winder is to EnergySolutions as Kirstie Alley was to Jenny Craig and Joe DiMaggio to Mr. Coffee — a shill, a mouthpiece, a flack. Sort of.
