Need book recommendation from 20th century people

Let’s suppose I’m putting together a syllabus for an American History II survey. I want to have a twentieth century focus and I desperately want to use Edward Larson’s Summer for the Gods. (Wouldn’t plan to have a textbook aside from Major Problems.) The Scopes Trial encapsulates so much about American culture: scientific confidence and religious fundamentalism, modernism and tradition, liberalism and conservatism, provincialism and metropolitanism, popular culture and the media, and all that. The book is highly readable and academically sound.

I want to use a second book that will resonate with Summer for the Gods, but has the rise of the modern conservative movement ca. 1968-now as its subject. It has to be accessible to freshmen and sophomores, so shouldn’t be an academic monograph.

I’ve thought about J. Brooks Flippen’s Jimmy Carter, the Politics of Family, and the Rise of the Religious Right, or Darren Dochuk’s From Bible Belt to Sunbelt, but haven’t looked close enough at those to know if they’d work, and fear they might be above freshmen. So that’s where I’m thinking.

Any suggestions? If I use your recommendation, you will have as a reward the undying enmity of my theoretical young scholars.
