I listen to current event and political podcasts quite a lot and recently I have started listening to the ones produced by Jacobin Magazine. These podcasts are usually thoughtful and fairly often on a topic that interests me. Still, they produce a number of shows, the episodes are often lengthy and it is hard to find the time to listen to all of them.
The current show in their program called The Dig I found to be a particularly thoughtful discussion of the situations that both the Republican and Democratic parties in the United States and if this is a topic that interests you then I would recommend it to you. Be warned that the discussion lasts for nearly two hours, however.
