Pew study finds Americans more polarized than ever

American adults are less likely to compromise and often decide where to live, who to marry and who their friends should be based on what they already believe. Michael Dimock of the Pew Research Center and Amy Walter of The Cook Political Report join Gwen Ifill to assess the data.
