Always a good question.
Given that the survey was done by the Wall Street Journal/NBC News, both of which are (still) supposed to be respectable and professional news organizations, one can only assume/hope they know how to make a selection without a (deliberate) bias.
Yes, that's my take on it until proven otherwise. I did wonder about your initial link, and thought that perhaps a lot of information was 'lost in translation' for that publication ("A majority of people in the United States say " without an immediate disclaimer about sample size and methodology). So I decided to wait for the actual survey to become available.
Unfortunately, the potential order of questions and wording of this particular question is actually worse than I had imagined (based on the second link).
“
news media and other elites” is already strange, and more so after the earlier questions. "And other elites"? I thought, what was the survey about then, the media, which elites, both?? "Exaggerating"? What do they mean? Too much coverage, or inflating the numbers, or ...? "because they are uncomfortable", is it about being uncomfortable? "and threatened", what about uncomfortable but not threatened or vice versa? "kind of change" could mean different things to different respondents. "that Trump represents", he does represent more than change alone, given his locker room talk and the violation claims by multiple women, to name only one aspect of his personality.
And then the length of the multiple interpretable question, was is asked by phone, as a written interview, response cards, in the street?
Strange, strange, strange.
