We’ve been hearing a lot recently about a “New American Majority” of black and brown Democratic voters. Progressive whites, together with progressive people of color, reportedly make up 51 percent of all eligible voters today.

Steve Phillips is a civil rights lawyer and a senior fellow at the Center for American Progress. His new book, “ Brown Is the New White: How the Demographic Revolution Has Created a New American Majority,” addresses the opportunities and challenges created by this demographic shift. We spoke with him recently on “The Zero Hour.”
