Below are links to three C-SPAN Q & A podcasts that are helpful in understanding the past presidential election. They are listed in the order I listened to them. You could probably listen in whatever order you wish.
Author J.D. Vance discusses his memoir, [Hillbilly Elegy], about growing up in a poor, white family that has its roots in Appalachia.
Author and columnist David Cay Johnston talks about this book, [The Making of Donald Trump], in which he takes a critical look at the 2016 Republican presidential nominee.
Historian Nancy Isenberg talks about her book, [White Trash], which examines the history of the class system in the United States.
