This paper studies the impact of immigration to the United States on the vote share for the Republican Party using county-level data from 1990 to 2016. Our main contribution is to show that an increase in high-skilled immigrants decreases the share of Republican votes, while an inflow of low-skilled immigrants increases it. These effects are mainly due to the indirect impact on existing citizens’ votes, and this is independent of the origin country and race of immigrants. We find that the political effect of immigration is heterogeneous across counties and depends on their skill level, public spending, and noneconomic characteristics. (JEL D72, J15, J24, J61, R23)

移民的政治影响：来自美国的证据

本文使用 1990 年至 2016 年的县级数据研究移民到美国对共和党选票份额的影响。我们的主要贡献是表明高技术移民的增加会降低共和党选票的份额，而低技能移民的流入增加了它。这些影响主要是由于对现有公民选票的间接影响，而这与移民的原籍国和种族无关。我们发现，移民的政治影响在各县之间是异质的，取决于他们的技能水平、公共支出和非经济特征。(JEL D72、J15、J24、J61、R23)
