Fox News is subject to liability and lawsuits if they publish defamatory statements on their platform. And that statement by Pew says nothing about the leverage and influence that Twitter enjoys on the national conversation.

Twitter was crazy for Bernie, but Joe Biden won the primary anyway.

Twitter is a self-selected minority of power users. It isn’t “The place” for political discourse, it’s simply a popular online web forum. Facebook is likely at least as influential on politics as twitter is.

That's not real political discourse, that's programming. Also major networks regularly quote Twitter.

The thing Twitter has is that it is a public forum where people who disagree can meet. I'd hate for it to become an echo chamber like Fox news.

They practically do have a democrat on each show. Times have changed, and Fox News is not at all what it once was. They even hired Donna Brazile, famous for slipping CNN debate questions to Hilary Clinton in advance and then being given the job of running the Democratic National Committee.
