Hillary Clinton holds a 28-point lead over Donald Trump among likely millennial voters, according to a new national poll.

The Harvard Institute of Politics poll surveyed 18- to 29-year-old Americans, finding that 49% of young likely voters support Clinton and 21% support Trump. Libertarian Gary Johnson received 14% and Green Party candidate Jill Stein received 5%.

Clinton has spent months reaching out to young voters, trying to capture the support Bernie Sanders received from millennials during the Democratic primary. Less than two weeks from Election Day, polls show a growing enthusiasm for Clinton among young voters.

While both candidates still struggle with strong unfavorable ratings, young voters’ view of Clinton has improved since July, when just 31% viewed her favorably and 60% viewed her unfavorably. In the new Harvard poll, 40% of respondents found her favorable and 53% found her unfavorable. Just 19% viewed Trump favorably, while 73% viewed him unfavorably.

An overwhelming majority of young Hispanics (72%) and African-Americans (85%) said they believed people of their own racial background are under attack in the United States, according to the survey. A majority of millennials (62%) said race relations would worsen if Trump is elected president. By comparison, 36% said race relations would stay the same under a Clinton presidency and a roughly even number thought relations would improve (23%) or worsen (22%).

The poll—which surveyed 2,150 young adults, ages 18 to 29—was conducted between Oct. 7 and Oct. 17. It had a margin of error of plus or minus 3.1 percentage points.
