In a marked reversal from a year ago, more Americans now have positive views about immigration, and a record high believes it is good for the nation.

About 8 in 10 Americans, 79%, say immigration is "a good thing" for the country today, an increase from 64% a year ago and a high point in the nearly 25-year trend.

Gallup found that 62 percent of Americans disapprove of Trump’s handling of the issue, and there are signs of erosion among Republicans, too.
