I'm not sure of the politics in the Wiemar Republic. How many Jews supported the National Socialist party? How many of them voted for the National Socialists during the Great Depression economic crisis? (Not many, I suspect. Voting against a group is, by definition, not supporting them.) (https://www.yadvashem.org/odot_pdf/Microsoft%20Word%20-%2077...)

Once the National Socialists had achieved power, in 1933, German Jews protested the actions of their government, leading to the Civil Service law and further restrictions on Jewish activities. (At this time, there were many German non-Jews who probably didn't like their government's activities but benefited a great deal from those activities.) By 1935-36, Jews in Germany had essentially no power, either to support or oppose the government. (https://en.wikipedia.org/wiki/History_of_the_Jews_in_Germany...) Thus, those who could left.
