It always bothers me that I know American politics presumably pretty well but my own nation's politics on a nearly surface level so I guess I'll ask this, but this can be for practically any country that isn't the US or maybe Britain.

Since this is specifically for your countries the sources can be limited to your country's language.

One source of Brazilian (my nation's) news I've heard of that isn't a from a large cable channel like CNN is Nexo, although the paywall makes serious consumption inviable simply because my parents wouldn't pay for me to read news of all things, but if you can, do it, the charts are great and the rest seems pretty good.

I find this to be a pretty important question when news organizations like Fox News are literally aiming to help the Republican Party to stay on power, CNN and MSNBC promote centrist candidates and media aggregators ranging from r/the_donald to r/chapotraphouse banning anyone who opposes them. Thing is, these are the most well known examples. How could we tell faulty media sources and aggregators apart from good ones in mass? Do you think that's possible?
