I don't have a Nebula account, but I checked their feed a while ago and they seem to have a variety of opinions, at least for videos about politics/economics.

I don't have a Nebula account, but I checked their feed a while ago and they seem to have a variety of opinions, at least for videos about politics/economics. I found both socialist channels (eg. "Second Thought") and liberal/pro-market channels (eg. "PolyMatter"). I'm not sure if they have any right-wing/republican channels though, so if that's what you want, perhaps it is not for you
