Jason Silverman has done something rare: he's actually found something new to say about Abraham Lincoln.Jason is the Ellison Capers Palmer, Jr. Professor of History, Emeritus, at Winthrop University. His new book, "Lincoln and the Immigrant," explores Lincoln's attitudes and actions toward those who made their way to our shores in the mid-Nineteenth Century. This is history, of course, but Jason thinks that perhaps Lincoln has something to say to us about immigration today.
