Now, you can choose to convince yourself that this only happens because we're some backwards, ex-communist backwater, but you'd clearly be wrong. The reason news sources with different ideological slants look different is because they pick their stories and how to present them differently. I fail to see how this would be controversial.
And we also know from the DNC emails that they conspired with news organizations to ignore Bernie and play up Trump (part of their lose lose campaign).
