The National Rifle Association, one of the most powerful Washington lobbying organizations, is seeking a new communications director to replace out-going flack Bill Powers. Applicants for the job -- called the third-most hellish PR job by PR Week readers -- would look forward to handling PR for NRA president Charlton Heston and to presiding over one of the largest stockpiles of PR dollars. The group spent $100 million on PR and advertising last year. Former communications director Powers left the NRA to join The Mercury Group, the PR agency of record for the NRA.
