I've wondered about this for a long time as well. The area in which I live in Southeast Missouri is predominantly of German American heritage. In my county alone, there is a tiny community of Dutch-German Catholics and this is one of the most staunchly Republican precincts in the county. The "town's" baseball field is littered in pro-life banners.
Osage County, Missouri is also strongly Republican and heavily of German American lineage; in fact, I think they even have some of their street signs in Germanic names. This is a part of the state that is included in the Missouri Rhineland.
Osage County wasn't swept by Republicans this year, they voted for Koster for AG.
And Osage County was one of the few non-confederate counties to vote for Kennedy and Goldwater, also mainly due to German Catholics.
So your area would be Perry County, or somewhere in the vicinity?
