His dark message of decline doesn’t resonate among voters with college degrees.

Why Trump Is Failing With College Grads

The support of white voters with a college education is the key battle of the 2016 presidential contest, and Donald Trump is losing it. In 2012 Mitt Romney beat Barack Obama by 14 points among college-educated whites, according to exit polls. The average of top national surveys shows Mr. Trump trailing Hillary Clinton among these voters by nine points, and the latest Pew Research Center survey gives Mrs. Clinton a 14-point edge.

Unfortunately for Mr. Trump, these voters are more important than ever. As recently as 1988, whites without a college degree formed 54% of the electorate, compared with only 31% for whites with a four-year degree or more and 15% for nonwhite voters. A Center for American Progress analysis shows that by 2012, the noncollege white share of the electorate had fallen by 18 points to 36%, while college-educated white voters had risen five points to 36% and minority voters nearly doubled to 28%.
