CNN and Fox both ran AP stories on the promotion of Karl Rove in Bush’s administration. The headlines show different perspectives and, as I have noted before, I believe that headlines can shape the readers viewpoint. Here is the common first sentence from both articles followed by their respective headlines:
Karl Rove, the senior political strategist who orchestrated President Bush's re-election campaign, has been promoted to deputy chief of staff, a job that will involve him in most White House policy and not just politics.
CNN headline: “Rove's new position will involve policy” following by a smaller font headline, “Promotion rankles a few Democrats”
Fox headline: “Rove gets promoted to deputy chief of staff”
Fox emphasizes the promotion with its headline and notes the new title. No emphasis is placed in the headline about Democrat reaction. CNN emphasizes that Rove will now be involved with policy decisions as opposed to his political role before. Democrat reaction is noted in the sub-headline. Both headlines are accurate but show different biases.
[Side note: Fox’s article is shorter and does not contain a paragraph that gives more details on Rove’s duties. CNN’s article, and AP as well, have that paragraph plus a list of other staff changes.]
