Most Americans oppose the separation of immigrant families at the border, and a larger share of people than at any point since 2001 say immigration is good for the nation.

Those were just some of the findings of polls published in the past week that shed new light on attitudes toward immigration, a subject that many Americans view as a top concern ahead of this fall’s midterm elections.

While most oppose President Trump’s policy of separating children from their parents at the border, fellow Republicans were more likely to support it than not, the polls found. Since the polls were conducted, however, the president caved to public pressure and agreed to stop the separation policy by detaining families at the border together for an indefinite period.

And despite the president’s anti-immigration message, three in four Americans say immigration is generally good for the nation, according to Gallup, the polling organization.
