George Johnson, Democratic candidate for Anne Arundel county executive, has resurrected the specter of electric deregulation in a new ad attacking Republican rival Del. John Leopold?s voting record, characterizing him as a pawn of utility companies.

The ad, which began running on cable television throughout Anne Arundel County on Tuesday, touts Johnson?s record of efficient management of the sheriff?s department that resulted in the return of $1 million annually to county coffers.
