Rural law,  rural voters

Lisa Pruitt, professor of law, explores rural-urban differences in relation to how people engage law and the state. Her central premise is that law and legal scholarship have become metro-centric and that most lawyers and law professors, along with many judges, know little about rural people and places and how they differ from what has become the implicit urban norm. Pruitt has since brought a ruralist lens to myriad legal topics, among them abortion access, substance abuse, termination of parental rights, domestic violence, access to justice, health and human services, and indigent defense. 

In 2020, she wrote about J.D. Vance's memoir, Hillbilly Elegy, in The Conversation, finding his characterization of poor rural whites compelling but too focused on personal responsibility.

Pruitt has also written extensively on Article 14 of the Convention on the Elimination of All Forms of Discrimination Against Women, of which Article 14 guarantees particular rights to “rural women.”
