This person didn't vote for Trump but, although she voted for Sanders in the primary, she didn't vote for HRC either. So she wasn’t a cultist on either side.
She has good memory and in ‘16 listen/read all the “liberal” sources. When the narrative started to fall apart (and if you have good memory you saw it fall apart) she started giving an ear to “alternative” media.
She eventually reached the conclusion that the alternative media was more honest.
Take from this anecdote what you will, but these people are out there (they’re referred to, obnoxiously, as being “red pilled”) and when elections are won on the margins, they matter.
