To me this was both wrong, since it basically ignored the basic responsibility of the media in our civilization, and counter productive, since it was so obvious that they were 'in the bag' that people stopped trusting the major news outlets entirely and started getting their 'information' from non-traditional sources, like the alt-media, social networks, etc.
So you can say that everyone is a bunch of 'whack jobs', but it seems like we have a competition here between the 'traditional media' who are being incredibly dishonest and more or less repeating talking points from the DNC, the 'marginally traditional' media like fox news, which is just as much in the bag for the right and so also not really a trustworthy source of information, and the 'other stuff' people are now getting information from, which is just a total mess of false information and unsubstantiated conspiracy theories mixed into all the actual things going on in the world.
So if you want to blame someone, blame the traditional media, of all the things that happened they were the only ones who abandoned their responsibility, and everything else followed from that.
