It sounds tinfoilish but it’s true - the news media that most Americans get their news from don’t want to talk about (mainly because the broken system we have is to the benefit of the companies who own them).

Also, a depressingly lot of voters only have an issue with the two party system because it’s one party too many, not too few. Each party (though one in particular imo) has spent the last few decades convincing their base that they’re the only thing standing between them and chaos. I’d wager a lot of voters would be terrified at the notion of third parties actually gaining power
