Recent elections outcomes have made many Americans question the accuracy of public polling. Political polls for the 2016 and 2020 presidential contests, for example, generally underestimated the support for former President Donald Trump. In many ways, measuring public opinion is more difficult than ever, but polls are still often accurate. They also play an important role in giving residents voters a voice and informing policymakers. With another presidential election looming, Christian Grose, a USC Price School professor and academic director for the Schwarzenegger Institute for State and Global Policy, joins the show to discuss how polling works, how it's evolved, and how pollsters are approaching the 2024 race.
