I'm a historian, and I write about a great many subjects: presidential studies, political ideology, economics, architecture, film, historic preservation. I taught at Washington College in Chestertown Maryland for thirty years. I'm a maverick independent, a free thinker, and I like to work "outside the box." Besides my books -- Father Abraham, Lincoln's Way, Lincoln and Race -- I've contributed to the New York Times "Disunion" on-line series on the Civil War, and I've written op eds for the Washington Post, CNN.COM, and History News Network. I wrote two cover stories for The American Scholar magazine.
