Four years ago, Atlantic City Mayor Lorenzo Langford told voters he would not run for re-election. On Tuesday night, the 57 year-old Langford announced his run for a third term in office from his campaign headquarters. Langford said the creation of the Tourism District and dealing with effects of Superstorm Sandy changed his mind about staying in office. The mayor plans to unveil a three-point residential property tax relief initiative in the near future. Langford will face Atlantic County Freeholder Charles T. Garrett and retired Atlantic City police officer David Davidson in the Democratic primary.
