My other post was flagged for sensationalism, so I slightly modified the title. This title actually does describe what is actually in the article (at the end).
I believe you should be using the title from the article as is, when it fits. Anything else is editorializing and frowned upon on HN.
Usually I do that, but in this case the title was almost meaningless ('How the Media Could Get the Election Story Wrong'). I wanted to highlight the bit I found interesting.
