I will say that politics is often newsworthy and this community definitely has a US skew. Those things combined mean we do have a lot of US political content.
I acknowledge that a significant volume of the political content comes from a few specific posters (not gonna name them but I think you know at least one of them). That isn’t necessarily a problem, unless all of the content from a given user is about the same topic. That’s when it approaches propaganda and becomes problematic. Opinion pieces should go on politics-specific pages though, per Rule 6.
