In this enhanced audio version of "American Voices 2024," FRONTLINE follows the changing views and experiences of Americans from the 2020 election season to the present day. The documentary returns to voters first featured in 2020’s "American Voices: A Nation in Turmoil" as they dealt with COVID-19 in their communities that spring, responded to George Floyd’s killing that summer, and experienced the polarizing election and its aftermath that fall. "American Voices 2024" chronicles how their hopes and fears have changed over the past four years — and amid another polarizing election season.

FRONTLINE investigates the lives and views of Sen. JD Vance and Gov. Tim Walz as they run for vice president. In a historic election, those who know the candidates best reveal the influences and ideas they would bring to the White House.
