This book does not tell a new story. It is commonly understood that the evangelical political movement did not organically organize around opposition to abortion, but was woken from its Benedictine slumber by rulings that eliminated tax exempt status for whites-only schools, better known as segregation academies. Abortion was picked as the issue to speak about more publicly because the real inspiration was rather icky.
What is interesting is that Balmer grew up within the movement and has personally spoken with key figures like Paul Weyrich and was present for someone of Reagan’s less subtle dog whistles. It’s a short book, but while not an exemplar of style, does provide a pretty interesting and often insider’s view of the meetings and events that led to the evangelical movement becoming a right wing political movement, leaving behind, along the way, the social justice teaching of Christ.
