When my husband and our 15-year-old decided to campaign for Barack Obama in the North Carolina mountains near my parents’ home, I thought our daughter would come away with some early schooling in the arts of organizing and good ’ole shoe-leather politicking. BusinessWeek’s ethics code prevents me from campaigning or showing my political stripes, but that prohibition doesn’t extend to my family. And so, we thought, our high school sophomore would get the civics lesson of her life.
