The largest, and most prosperous, immigrant group here is Asian Indians, who work almost exclusively in the IT and Software companies.
We also have a large Filipino immigrant group.
They are mostly blue collar, but, surprisingly, they vote about 40%-45% Republican.
The Asian Indians, in spite of high education and high salaries, vote 90% Democrat.
Finally, we have one of the largest Russian expatriate groups in America (Ukraine mostly).
They are mostly blue collar, and I’ll guess they vote Socialist, since they often look really unhappy at work.
We have almost no American Blacks and just a small percentage of Hispanics.
I wouldn’t be so sure of the Ukrainians. They know first hand what communism is and the path that gets them there. My kids are taking Ukrainian dance lessons and, at least the people I talk to are very conservative, especially a woman college political science professor.
