Yes, racial resentment is the strongest predictor of the Obama-Trump vote in this survey data. White, working-class Obama voters with racially conservative views were very likely to flip to the Republicans. For example, Mrs. Clinton won just 47 percent of white Obama voters without a college degree who disagreed with the idea that white people in the U.S. have certain advantages because of the color of their skin. In contrast, she retained 88 percent of white Obama voters without a college degree who agreed that white people have certain advantages.
Nonetheless, voters with high racial resentment did not necessarily represent the preponderance of the Obama-Trump vote, because Mr. Obama had already lost nearly all such voters by 2012. To take the prior example: 49 percent of white, no-college Obama-Trump supporters at least somewhat disagreed with the notion that white people had certain advantages.
