No, I don't think that would be an appropriate headline in that case. But that is somewhat of a red herring/straw man since I am sincerely doubtful that was the first headline they put up. More likely that came a day or two after the story broke. And in that case, it would be appropriate.

You'd be surprised how many people follow politics as if it were sports. The politic tactics surrounding the story are an angle that their readers are interested in, and they have real consequences as well. I think you'd have to consider all their coverage of the story as a whole to analyze their slant (which is Democratic, of course.)
