What went wrong with polling in 2020
Political polling is under scrutiny once again. While pre-election surveys set expectations of a Democratic landslide, the presidential contest and many Senate and House races came down to the wire instead. In fact, Republicans gained ground in the House. To understand what went wrong, Judy Woodruff talks to pollsters J. Ann Selzer of Selzer and Company and Chris Kofinis of Park Street Strategies.
