Nine in ten Republicans say increasing border security is important, and immigration remains a salient issue with voters entering the 2022 midterm elections.

But it's not just general opposition to immigrants that registers with voters. The skills immigrants bring shape how US voters view them.

In a paper in the American Economic Journal: Applied Economics, authors Anna Maria Mayda, Giovanni Peri, and Walter Steingress investigate how Republican vote share changed with an influx of differently skilled workers. They say that Republicans lost votes in places where the immigrants were highly skilled, for example, in fields like health care or IT, while gaining vote share where there was an influx of low-skilled foreign workers.

Additionally, they find that if overall immigration—including all skill levels—had been cut in half in certain states between 1990 and 2016, it would have swung the 2016 election for Democrats.

Mayda spoke with Chris Fleisher recently about how immigrant skill level shapes public perceptions, the extent to which this affected Republican support, and the implications for how immigration is talked about by policymakers and covered in the media.
