"Zinnophobia"

Today:   Purdue University Northwest professor David Detmer joins us to talk about his latest book, "Zinnophobia: The Battle over History in Politics and Scholarship."  It focuses on the famous author Howard Zinn, his teachings and books that looked at bias and objectivity in history, and how then-Governor Mitch Daniels wanted to ban the teaching of one of Zinn's books in Hoosier schools.
