Meacham was asked to speak at the 2020 Democratic National Convention on the Soul of America. He endorsed Joe Biden, saying, "history, which will surely be our judge, can also be our guide. From Seneca Falls to Selma to Stonewall, we're at our best when we build bridges, not walls". According to "The New York Times", Meacham has been part of the team, writing some of Joe Biden's speeches for the 2020 United States presidential election, including Biden's acceptance speech.
