The right answer is D. newspaper article.
In order to decide the best option let us understand what an objective view means. It means that the presidential campaign will be evaluated by a media that will not add a personal overview, a biased interaction between what is really true and factual and the subjective ideas of the journalist.
A. Newspaper editorial - False - The main point of this kind of newspaper is to have the editor's opinion about the article. As illustrated before, an opinion is not an objective view.
B. Personal journal - False - A personal journal is also a biased source, given that it is also structured to be personal.
C. political speech - False - Political speech does not qualify because it also expresses one biased opinion. In this case one political inclined position.
D. newspaper article - True - Newspaper articles do qualify because the main point is to express the fact, in this case, the presidential campaign, as objective as possible. In order to leave the reader, decide his own opinion about the campaign.
