On the other hand, the Nazis made little effort to prevent either the casting or tabulation of negative or invalid votes in districts that were known to have large populations of Jews, Poles and other ethnic minorities. As was the case in November 1933, the Nazi leadership considered the expected unfavourable results in such areas to be useful in their propaganda as proof of disloyalty to the Reich. This was the last national vote in which Jews and other minorities were allowed to cast ballots prior to their being stripped of citizenship rights the following year upon enactment of the Nuremberg Laws.[citation needed]
