Marcus Ferrell, a political organizer from Atlanta, tells Radio Hour about the importance of turning out "unlikely voters" in order to win an election, which, for him, means black men. Jelani Cobb, a New Yorker staff writer and historian, points out that the four Democratic front-runners, all of whom are white, may struggle to get the turnout they need. Cobb tells David Remnick that Joe Biden's strong lead may begin to fall after his weak showing among largely white voters in Iowa; Pete Buttigieg has very low support among South Carolina voters, and even faces opposition from black constituents in his home town, South Bend. But Bernie Sanders, Cobb says, seems to have made inroads with at least younger black voters since 2016. Plus, a New Yorker staffer picks three favorites.
