Hillary Clinton's Lead Among Nonwhite Voters Surges

The gap has widened in the latest national poll.

An ABC News/Washington Post poll released Sunday has Clinton leading among nonwhite voters by the biggest margin yet: 77 percent of nonwhite voters side with the presumptive Democratic nominee, compared with 15 percent who prefer her Republican counterpart.

"It is white voters overwhelmingly for Donald Trump, nonwhite voters overwhelmingly for Hillary Clinton. Older voters for Donald Trump, younger voters for Hillary Clinton. The educated voters for Hillary Clinton, high school voters for Donald Trump," he said.

While Trump has maintained a lead among white voters, the gap there is shrinking. In a March ABC News/Washington Post poll, Trump had a 9-point lead among white voters; that margin went up to 24 points in May but is now down to 10 points.

Meanwhile, his deficit among nonwhite voters has been larger throughout. Clinton has consistently held a lead in that group.

In the March poll, she received 73 percent of the vote preference among nonwhite voters, compared with Trump's 19 percent.

That gap decreased slightly in late May, when the overall poll was effectively a dead heat, with Trump at 46 percent and Clinton at 44 percent. In that poll, she led among nonwhite voters, 69 percent to his 21 percent.

This latest ABC News/Washington Post poll shows that she has gone back up among nonwhite voters, opening the biggest gap yet.

That controversy, coupled with Trump's regular calls to build a wall along the U.S. border with Mexico, has Latino voters uneasy.

J. Santos Trejo is one such voter in Texas. He is a 42-year-old landscaper in Houston who became a U.S. citizen in recent years after arriving from Mexico more than two decades ago.

Trump "is talking too much about Latinos," he told ABC News.

Trejo said he doesn't know whether Trump "really means" what he's saying "or if he's just talking like that to be famous. I don't know what he's thinking in his heart."
