SPOTSYLVANIA COUNTY, Va. — Peggy Hayes is professionally upbeat. A personal trainer, she teases clients about the pain that awaits them and hands out calling cards that read: “Clear your mind of can’t.” Yet beneath her motivational smile lies something much less confident, and it’s had a deep impact on her political views. Lately, so many prospective clients have been canceling their training sessions that the owner of a gym where she works has started calling her “Bad Luck Peggy.” Hayes, 53, offers free consultations and shows clients how to make protein shakes with egg whites.
