Politics, Portraits

On today’s show: Mark Meckler and Jenny Beth Martin tell us how they became the faces of the Tea Party Patriots. We’ll hear about a new exhibit of Renaissance portraiture at the Metropolitan Museum of Art. The BBC’s A History of the World in 100 Objects continues with a look at a sculpture from the Parthenon. Plus, our word maven, Patricia T. O’Conner, takes your calls on the English language.
