You make my other points for me here. You have already concluded that Hillary's trait is not uncommon and not disturbing to others. Therefore defending/debating (your feeling not mine) why they have not written about it. To be fair and honest to both sides there is absolutely no reason why they can't write about her disturbing bug eyes nor her fake annoying laugh. But the fact is they won't. They are a LIBERAL RAG that only writes about traits of conservative candidates as a hack job. Since they have 6 articles hacking both Cruz and Trump and none hacking Hillary nor Bernie you really don't have an argument here.
If there is nothing of psychological reference about Hillary then what are they supposed to write? This is not to say that your question is invalid, rather, that absence of a psychological examination of Hillary is not proof of bias.
Here is an article from this publication admitting their LIBERAL BIAS:

https://www.psychologytoday.com/blog/rabble-rouser/201310/liberal-bias-in-social-psychology-personal-experience-ii
The articles admit to a bias in the field, but not to the publication or the author in question. Again, doesn't mean there wasn't bias, but it isn't proof that this piece was biased.
On top of that, the existence of a bias does not mean the work itself is less than objective. Nearly everyone has some level of bias, but a good professional can eliminate it or significantly reduce its impact. Furthermore, even if there is a bias in who they choose to write about does not mean that what they write is inaccurate.
But ok, so lets say there is bias in the piece. You have bias as well, so why should I take your arguments that this is bogus over the arguments of someone with credentials? The argument you use to discount the piece discounts your own comments as having any authority as well. Essentially if we run around pointing to biases saying it makes the source unreliable, then we could never believe any news source, study, or report.
It may be circumstantial but far from a weak argument when you make my point with your own words: "It wouldn't make sense to run it when they weren't famous since few would care."
EXACTLY If they meant to write an article about how JOE BLOW's mouth makes disturbing motions I could see how it might be interesting. But it is WHO they chose and WHEN they chose to run it plus your own words validates exactly what I said. Not to mention they wrote 6 hack jobs about Cruz and Trump and none about Bernie nor Hillary. And they admit to their own liberal bias.
Fine, then if everything you say is absolutely true then delete the link you posted and post a link from Psychology Today with a similar topic that is not about a recent presidential candidate and I will believe that you didn't post this as a way to do a hack job towards a conservative candidate.
But they haven't and they won't. Again, making my point for me. thanks!
I don't believe there is anything else for us to discuss here so I am calling this one quits as well. 
Did you do a search before posing that challenge? A search for meanings of facial expressions turned up 5 pages of articles touching on various aspects. If you want specific links I can post them.
And I wont retract the original piece because the whole point was to discuss psychology relevant to voting! I could care less which candidate they wrote such a piece about. This was a segue to the topic at hand.
