With the increasing polarization, there will have to be some point. For example, right now, Fox News at least mention negative news relating to the president, and the NY Times at least acknowledge Trump's existence.
In the future, I predict the newspapers will be naked propagandists. If they judge that some thing someone says or does is going to be bad for their party, they will just ignore it outright or lie about it.
In 2016, Fox News had people criticizing Trump, and CNN were (unintentionally) signal-boosting him by letting him dominate the news coverage. In say 2024, I think that Fox News will fire anyone who says anything bad about the Republican nominee, and CNN will not mention them by name on air.
