Yes, the German Jews did assimilate easier, and were much more conservative. I remember in college when I was a poll worker in a GOP precinct worker in Chicago (in 1970), a well dressed German Jew lady of about 85, telling me about the glory days of Republican rule of some mayor of Chicago in the 1920's named Thompson (as a sidebar, the guy who said that if the King of the UK ever came to Chicago, he would hang him), and about the importance of property rights. LOL. But in Cincinnati, their considerable numbers were never cut by the Ashkenazim, and they become part of the GOP establishment.
Interesting anecdote.
