Ethnic Politics

I would tend to assume all of these groups would lean Democrat, but I'm far from certain.
Poles might be mixed due to the fact most are staunch Catholics. Russians also might be fairly mixed as they're pretty conservative.

The distinctions in some of the groups mentioned are pretty blurry. If you are focussed on first generation immigrants then some of the categories make sense. As you move to successive generations, factors involving region, income and education begin to outweigh historical ethnicity. Americans of northern European descent are almost impossible to peg this way. The Reagan democrats were often those of southern and eastern European descent, and it was clear that they were much less driven by ethnicity than was previously believed.

If you're from Philadelphia you know who I mean!!!!  Bridesburg, Mayfair, Port Richmond, Fishtown, etc.

I can't speak about Philly, but in Chicagoland, particularly in the suburbs, the voting distinctions due to ethnicity are basically gone. It's been too many generations since immigration. New immigrants around here do show voting patterns based on country of origin, but it washes out over time.
