Is this a rhetorical question? The media--be it news, sit-coms, movies, internet, etc.--can put a "spin" of almost anything. In films as far back as the 1950s there were subtle and some not-so-subtle persuasive techniques used to influence the thinking of the populace in the U.S. and other countries.
As an example of how the media treats different political parties, watch CNN News and then watch Fox News. There is a selectivity to what they present, and a certain slant How this news is presented by these liberal and conservative stations. And, as Post #4 mentions, what subject matter is even presented varies. If a president commits a faux pas, for example, it depends upon which party he is in with respect to how the press treats his error. For instance, one Repulbican vice-president was lampooned for a long time about his misspelling of potatoes while a Democratic president who thought there are 57 states in the U.S. had his mistake fade quickly from the public's notice.
