Yes, the mass media has done a poor job of covering the election because they should discount Trump's candidacy. The media treats him as if he is a serious politician. He is not. He is simply playing on the fears of uneducated voters. The media should reveal this to the people.
The media are essential to democracy, and a democratic election is impossible without media. A free and fair election is not only about the freedom to vote and the knowledge of how to cast a vote, but also about a participatory process where voters engage in public debate and have adequate information about parties, policies, candidates and the election process itself in order to make informed choices.
The mass media has done a poor job of covering the election, because they have biases. Because of their biases, they hold back on information that they think is helpful to their position, and then they release it at what they perceive is the right time. The Drudge Report used to be a great source, but he is so obviously biased for Trump that he's no longer a reliable news service, for example.
The only problem here is that when , one side is criticized, or the dirt linen is brought out in the open then the mass media will be deemed unfair. The media had done a good job exposing candidates form both aside and from this people are able to draw a conclusion and make an independent decision on who can better serve as President.
