WASHINGTON, D.C. -- As a whole, Americans' attitudes about immigration haven't changed significantly since Donald Trump's presidential campaign platform promised action against illegal immigrants. U.S. adults remain about as likely to say they would like to see immigration kept at its present level (38%) as they are to say it should be decreased (35%). About one in four say immigration should be increased (24%).

These data, collected in a June 7-11 优蜜传媒poll, are similar to from when Trump was campaigning for president. Since his election in November, Trump has reaffirmed his pledge to build a wall on the U.S.-Mexico border. He also had recent success with immigration policy when the Supreme Court decided to allow some aspects of his program for banning travelers into the U.S. from six Muslim-majority countries. But Trump's well-known stances on these issues, which propelled him as a presidential candidate, have not had any meaningful effect on Americans' preferences for U.S. immigration policy.

Fewer Republicans This Year Favor Less Immigration to U.S.

Republicans' and Republican-leaning independents' appetite for decreased immigration has fallen since Trump's election. Whereas six in 10 wanted less immigration last year, this figure is now slightly less than half (48%).

Republicans' substantial drop in desire for an immigration decrease is balanced, however, by small increases among Democrats and Democratic-leaning independents, as well as independents who don't lean toward either party. Both groups edged up three percentage points in their preference for a decrease in immigration.

Democrats' and Democratic-leaning independents remain most likely to say immigration should be kept at its present level (42%), while a third say it should be increased (33%) and 23% say it should be decreased.

GALLUP

The shift in Republicans' attitudes could reflect a sense of political victory among Trump supporters who believe the president is fulfilling the immigration-related promises he made on the campaign trail. Republicans could, thus, feel more satisfied with the current status of immigration than they did during the height of the presidential election. Also, some Trump supporters might believe immigrants are being more thoroughly vetted by the Trump administration.

Bottom Line

Though preventing illegal immigration was one of the president's key campaign promises, the general desire to decrease immigration is near its historic low in Gallup's trend over more than half a century.

Among Trump's own party, the decline in the percentage of Republicans who prefer to decrease the level of immigration into the U.S. could be related to a greater trust in federal vetting of immigrants rather than a decline in their concern about potentially dangerous immigrants entering the country.

However, more Americans may want to decrease immigration if they begin to feel the administration has wavered in its commitment to stricter immigration policies. Trump's pledge for a border wall, for example, will be politically challenging to fund.
