Who was the media biased for in 2016?

[Sumner 1868]

During the election there was numerous claims that the media was biased.

Supporters of Hillary Clinton claimed that the media was biased against her by focusing excessively on the story of her e-mails, digging up past scandals, and attempting to deliberately create a "horse race" narrative that didn't exist.

Supporters of Bernie Sanders claimed through the primaries that the media was biased against him by portraying him as an extremist, overestimating Clinton's delegate lead, and giving him insufficient coverage.

Supporters of Drumpf, of course, continue to argue the media was biased against him. During the GOP primaries his various challengers frequently complained about the free air time Drumpf received from the media.

So which was it?
