Importantly, this survey question does not distinguish between legal and illegal immigration. While many Republicans, including Senate Majority Leader Mitch McConnell, are careful to say they support legal immigration, the party is nonetheless known for housing many outspoken politicians on this issue, such as influential Rep. Steve King of Iowa, whose anti-immigration rhetoric often does not distinguish between legal or non-legal status.
In a follow-up question that queried Americans who are dissatisfied with the current levels of immigration, the majority — 39% of U.S. adults in total — said they would like to see the level of immigration decrease. This ranks among the lowest level of Americans who are dissatisfied and express a desire for less immigration since Gallup began asking the question in 2001, even if it is nominally higher than last year’s 35%. The share of Americans who are dissatisfied and want more immigration (7%) was unchanged from 2014.
