Though Donald Trump has made anti-immigrant policies a cornerstone of his campaign, most of his stances don’t seem to resonate with younger voters. In fact, a new poll of 18- to 30-year-olds shows that millennials are rapidly becoming even more welcoming toward immigrants.

Just in the past three years, there have been startling shifts in how 18- to 30- year-olds feel about the foreign-born, according to a comparison of two identically worded polls from the Black Youth Project at the University of Chicago and the AP-NORC Center for Public Affairs Research.

“It’s a really big increase,” said Jon Rogowski, an assistant professor of government at Harvard and co-author on the report. “Young adults are becoming substantially more supportive of progressive and comprehensive solutions to the immigration problem.”

The greatest changes have been among white non-Hispanic millennials, who now overwhelmingly support laws that would help immigrants stay in the country.
