I've gone for "never" simply because it looks like both campaigns (and, with them, the media) are trying to turn that one word into a defining element of the election. On Trump's side it's faux outrage at how "ordinary Americans" are being smeared; on the Clinton side it's "no one's as deplorable as Trump, do you really want to be like him?"
It looks like the phrase will have endurance, much like "47%" and "I can see Alaska from my house" (yes, I know she never actually said that).
It's amazing she can see Alaska from her house.
