He’s doing a major tv interview tomorrow on abc, and he’s done some radio interviews I haven’t seen. Which maybe reach millions of average people who aren’t online, but also leaves empty space online to fill with speculation
Matt Ferrel posted in another reply in this thread that Biden did a radio interview. Except by the host's own admission the station is small. Nielsen estimates (as far as I can tell I'm not sure the numbers) that it has 400k listeners. But this interview was taped and aired at 6AM.
