And you forgot Kansas, too, which is a heavily German state (mainly Protestant, but some Catholics too) that is very conservative/Republican.
That's another fascinating nugget. The largest German ancestry cluster in Kansas appears to be around Hays - mostly Volga and Bukovina Germans, so a completely different story again.
Anyway, in 1988, Hays voted for Dukakis and in 1992 for Clinton, and the surrounding rural counties - also strongly Volga-German - only went narrowly Republican. Since then, the area has become more and more Republican, indeed.
I trace the largest fraction of my ancestry from the Volga Deutsch, and have quite a bit of genealogy. Strangemaps posted this a few years ago.
