Your linked article describes a WikiLeak where the Dems figured Trump would be easy to beat. Hence, the MSM gave Trump favorable coverage until the minute he secured the nomination. Since then they've been 91% negative in one study.

As usual, the Left was wrong to think Trump was a weak general election candidate. The media would have destroyed any Republican candidate, and Trump was easily the most appealing of the bunch. He is promoting modern or neo-conservatism, which is traditional Americanism (see Understanding Trump).

Micheal Moore, a far left Hillary supporter, said this last week that Trump will win because the forgotten people in our corrupt system are going to give an historic huge middle finger to the ruling establishment. I hope he's right.
