>an article isn't going to convince a political party supporter to switch sides for example //
Why not? Are you suggesting articles can't carry information that changes peoples opinions; that people are wedded too much to Party identity; or perhaps that only one article wouldn't do it?
It should be able to change someone's mind if that person were rational, open minded and the article contained some very revealing information. It should.
...But it won't, not in today's American politics. There's no nuance left, it's us versus _them_, entrenched political warfare. If the article says something bad about my party it's either: _fake news!_ or a smear campaign by _them_! If it says something good about their party it's ____-wing propaganda.
