That was the 1936 vote I believe, and I'm sure the Jews weren't voting by then, though I may be wrong.
What is surprising, as an American (with all of our voter apathy), was the high level of political interest in Germany during the period. The Nazi's and other parties campaigned hard for the votes at least until 1932. Life in many areas seemed to revolve around the various rallies, concerts, functions and other political activites as a form of weekly entertainment almost.
By 1936 Hitler had managed to solifdify his power, both through repressing serious political competition and, perhaps more significantly, by being in power during the economic recover (started by the SPD ironically) and promiting patriotism and Germanic pride. He also represented a comfortable return to an autocratic rule for a people who were still new to the republic/democracy concept after WW1, and who seemed to distrust the chaos and messiness such a system involves. Democracy is messy, but you have to accept that to have true freedom.
