She shifted her focus from a serial killer's obsession with left-wing-celebrities to a would-be serial-killer taking his ispiration directly from the left. She's all over the place!
I'm laying odds that was sarcasm....
My point is that it’s bad writing to introduce a second subject like that. You can’t assume that your audience is going to understand the reference, and even if they do, to add that second subject only a few sentences from the end of the article with no explanation about the connection or why the addition supports the article is sloppy. You need to show the connection at least, and keep the structure of the article balanced. The way it’s written, it’s almost as though she’s introducing a completely separate topic, and then dropping it. I don’t doubt that he’s relevant, but you wouldn’t know it from the article.
