Yeah, I’m German myself (great grandparents immigrated) and live in an aggressively German city, which also happens to be one of the most liberal cities in my state. I also know the majority of Germans are very embarrassed of our history and do as much as we can to remove ourselves from that part of history.
Whites inherently aren’t conservative. If we imported whites from Europe we would likely be more liberal since European politics is way further left than our “woke left”. Tell me you don’t understand international politics without saying you don’t. This theory that Germans are all still Nazis is ridiculous. Your map is flawed and so is your theory
Assuming that German Americans are likely to like nationalistic candidates is wild. These conclusions are drawn from strictly the Midwest which has had more conservative views throughout all of the US. Additionally the lifestyle/values of the Midwest make it more drawing for the people to vote for a conservative candidate. You have yet to provide evidence that recent Germans or Europeans as a whole are more likely to lean conservative
