Yes, Trump is stirring the pot on some well-earned criticism on the media for political gain. But his tactic would fall flat if Americans maintained trust in the media which they most definitely have not:

The post discusses the political polarization of the media but the Gallup data indicates that faith in the press has dropped steadily among independents, whose views are more closely aligned with Republicans than Democrats. In the most recent poll, Democrats have a 21% gap over independents and a 37% gap over Republicans when it comes to faith in the media. And why not? They like what they see.
They should teach Chris Wallace's moderation of the final Presidential debate in journalism school. That would be a good place to start.
