During the 2016 primary, I'd argue Bernie Sanders got more coverage than normal. He was behind in polling and in delegate count. He should have been getting none. But he got more than what I think his candidacy deserved, since a horse race is good for ratings, and the story of him vs Clinton made for the perfect one. This is all based on my observations, and no empirical data however.

I do think Sanders was shortchanged of some press coverage in this primary. I think that's changing as his chances of winning go up. I hope he's covered extensively, because I don't think most people are aware of some of his negatives, and as a front funner, his candidacy deserves our scrutiny.

You make a good point that there is an oligopoly of corporate press. I think that's something harmful to our democracy, and something we should be concerned about. I'm not sure what the solution is. For now, I just donate to public radio.
