The data also provide a profile of voting-eligible nonvoters. Four-in-ten Americans who were eligible to vote did not do so in 2016. There are striking demographic differences between voters and nonvoters, and significant political differences as well. Compared with validated voters, nonvoters were more likely to be younger, less educated, less affluent and nonwhite. And nonvoters were much more Democratic.
Among members of the panel who were categorized as nonvoters, 37% expressed a preference for Hillary Clinton, 30% for Donald Trump and 9% for Gary Johnson or Jill Stein; 14% preferred another candidate or declined to express a preference. Party affiliation among nonvoters skewed even more Democratic than did candidate preferences. Democrats and Democratic-leaning independents made up a 55% majority of nonvoters; about four-in-ten (41%) nonvoters were Republicans and Republican leaners. Voters were split almost evenly between Democrats and Democratic leaners (51%) and Republicans and Republican leaners (48%).
