Ethnic groups, assimilation and voting

[King of Kensington]

Which groups become more Democrat or more Republican as they become more assimilated?

Here's a guess for a few:

Jews:  Less assimilated more R (Orthodox and immigrants), more assimilated more D, though the most assimilated of all, Jewish Christians would be more R again.

Italian Americans:  Less assimilated more R, more assimilated more D.  Italians in the NYC area (which has more single ancestry Italians and a disproportionate share of postwar immigrants) seem significantly more R than elsewhere.

Arab Americans:  More recent immigrants are more heavily Muslim and Arab Americans in the past were more R than they are today.  I think it's fair to say that the predominantly Christian descendants of earlier immigrants are more R.

Dutch Americans:  Their concentrations in Michigan, Iowa and Washington State are very conservative and still belong to fundie churches, while descendants of the colonial Dutch in NY/NJ have completely melted.

Younger Cuban Americans are certainly a lot less politically conservative than older, foreign born Cubans.

How do 80s/90s Polish immigrants vote?

It makes obvious sense that the more assimilated, the closer to general American patterns.  Jews seems to be a partial exception.

I think in 1920 the Jewish vote was split between Harding and Debs!

The older German Jewish population was Republican in the past.
