Others have mentioned several subreddits; I would like to recommend r/NeutralPolitics. I occasionally browse it and I'm blown away by the quality of the discussion compared to the discussions at other popular political subreddits, e.g. r/politics. Neutralpolitics's success is probably due to its rules and moderation, which help promote constructive discussion, and its lesser traffic compared to other political subreddits, meaning that it doesn't suffer from the unconstructive comments that result from the popular audience.
