Weaponization of a candidate's words against him or her is something we're seeing a lot. The term Obamacare was used against Obama in a pejorative way, but Obama again reclaimed it.

When words come out of politician's mouth that are linguistically incorrect, people see it reflecting their intelligence. Sarah Palin was called out for "refudiate," which seemed to combine refute and repudiate. One favourite Bushism was "misunderestimate."

Donald Trump himself has an idiosyncratic speaking style that relies on simple words and phrases, which worked for him in the primaries but may be coming up short for him now.

Hillary Clinton has been portrayed as robotic, someone who is trying to approximate real human emotion.

Donald Trump speaks extemporaneously, often through stream of consciousness, where it doesn't seem to follow a trajectory.

Even if you close your eyes, you'll still hear Donald Trump sniffing. Linguists might call [these visuals] paralinguistics, every form of information including facial gestures and facial features. Obviously these things get scrutinized in tremendous detail, so that a cough can be of outsized importance. [But] that's all part of the package.

Even though a definite article is supposed to bring something into focus, Donald Trump uses it in a very general way. It's seen by many observers as a kind of racial distancing. Often using that article seems unnecessary. [But] it is serving some function, which is to represent a group collectively rather than as individuals.
