The Utah Foundation published its list of the top 10 issues for 2016. Health care, air quality, public education and taxes topped the list. Yet, in 2016 and 2018 and for almost as long as I can remember, the voters voted on none of these issues. If they had, Utah would have a much different government than currently exists.
This does not necessarily mean voters lie to pollsters, but rather pollsters may not ask the right questions.
