Surnames and voting

[Okay, maybe Mike Johnson is a competent parliamentarian.]

Dutch surnames appear to be the most Republican leaning (i.e. De Jong, Vries, Visser, De Boer, Bakker, etc.), usually over 60%. This is what I expected, given that Dutch Americans are known to be quite politically conservative.

Next are German and Scandinavian names (Schmidt, Hansen, Andersen, etc.), generally in the mid to high 50s.  White Midwesterners, mostly.

Italian names like Rossi, Russo, Volpe and Lombardi seem to be slightly Democrat, low to mid 50s.  Not sure if Latinos with Italian surnames are pushing it a bit towards Democrats, as Italian Americans are thought to be politically conservative (though on the other hand, they are concentrated in the Northeast and maybe this conservatism is overstated?)

Polish (Nowak, Kowalski) and Irish (McCarthy, Reilly, O'Brien, O'Connor) also lean a bit Democratic.

This is the case.

This is the case.

What happens on Staten Island stays on Staten Island?

It ought to, certainly.

In all seriousness, Italian-Americans as a whole are about on par with the country politically. In the Northeast you have places like Staten Island and the further-out parts of North and Central Jersey and parts of Connecticut, and then you have places like inner North Jersey and the predominantly Italian areas of Massachusetts, other parts of Connecticut, and Rhode Island, many of which are culturally 'conservative' by some metric or another but not in a way that makes their voting patterns markedly less Democratic.
