And then there were seven. The Republican field of candidates for the 5th District congressional seat grew yet again Tuesday to include former businesswoman and volunteer Penry Gustafson of Camden. Gustafson, 46, is a former sales representative for Delta Foremost Chemical Corp., a longtime Kershaw County GOP member and a community volunteer for such local and regional organizations as Meals on Wheels and Operation Inasmuch. Gustafson said she was running as an alternative to “today’s toxic political environment.”
