The language of polling may be numbers, but the stories it tells are about people. As Elections and Surveys Director for CBS News, it's Anthony Salvanto's job to understand what you think and how you vote. Parting the curtains on a mysterious process, Salvanto demystifies jargon and answers the biggest questions about polling and pollsters. How can they talk to 1,000 people and know the country? How do they know the winner so fast? And most importantly, why didn't they call you? Analyzing some of the major polls of the past 20 years, Salvanto offers data-driven perspective on the 2016 election, the response to terrorism, and the backlash against big money.
