I'm almost certain Obama won people of Scottish ancestry. It's the wealthiest ancestry group in the country, but they're heavily concentrated in New England and the rich-liberal parts of the NYC area.
OTOH, I seriously doubt Obama won Hungarians. True, most Hungarians in the US are Jews, but they're heavily Hasidic Jews, who vote overwhelmingly Republican in Presidential elections (like 90% McCain, probably similar for Romney). I don't think there are that many Reform or Conservative Jews from Hungary, and those are the Jewish groups that vote Democratic (plus Orthodox Jews outside of the NYC area).
There are very few self-IDed people of English ancestry in the South. It's basically New England (+upstate NY) and the Mormons. I think New England English would outvote the Mormons, but it's hard to say for certain.
I'm pretty sure of the recent European immigrants, Bosnians voted for Obama... Though I have no numbers to back that up.
They're Muslims. It would be shocking if they weren't at least 75% Obama, given recent trends.
