Love him or hate him (and, either way, you have lots of company) Ronald Reagan was, and continues to be, an important figure in American constitutional history.

We'll speak with Justin Garrison, a professor at Roanoke College in Virginia, who's written a balanced, fascinating, readable book called "An Empire of Ideals: the Chimeric Imagination of Ronald Reagan." Justin is that rare scholar who not only writes well, but also speaks well. He's even funny and charming - kinda like Ronald Reagan was.
