More than a year after President Joe Biden's inauguration, around two-thirds of Republican voters believe his election was illegitimate. How did a stolen election myth make its way to the center of American politics? Director and producer Samuel Black and correspondent A.C. Thompson, part of the team behind the 2022 FRONTLINE and ProPublica documentary "Plot to Overturn the Election," sit down with FRONTLINE’s executive producer, Raney Aronson-Rath, to discuss how a handful of people have had an outsized impact on the current U.S. crisis of democratic legitimacy.

The legacy of misinformation extends beyond the 2020 U.S. presidential election and the Jan. 6 Capitol riot, Black and Thompson found. “How is the ongoing battle over the last election threatening the next one?” Thompson asks in the documentary.

"Plot to Overturn the Election" is now streaming on FRONTLINE’s website, the PBS Video app and FRONTLINE’s YouTube channel. Want to be notified every time a new podcast episode drops? Sign up for The FRONTLINE Dispatch newsletter: https://www.pbs.org/wgbh/frontline/dispatch-newsletter-subscription/
