Foreigners tend to give very whacky answers on political polls regarding other foreign countries. It's a very different experience, foreign politics and domestic politics. GOPers never do well in them, but Democrats tend to dominate expat communities, so I'm not particularly surprised. At least from what I've experienced, European immigrants in the USA seem to actually be somewhat more right-wing than the average American (or about where the average White American is).
Of course, I've seen this phenomenon not just in America. Americans in East Asian countries have a tendency of backing batsh**t insane parties out of lack of information/lack of understanding of the country.
Russian immigrants that still speak Russian(post 1992) used to be 70% Democratic(before Obama).
