Like previous elections in Nazi Germany, it was characterized by high turnout and a massively lopsided result, with an official 99.0% turnout. In a publicity stunt, a handful of voters were packed aboard the airships Graf Zeppelin and Hindenburg, which flew above the Rhineland as those aboard cast their ballots.

Although the proposal was approved by 91.5% of voters, turnout was only 49.6%, resulting in the referendum being invalidated as the threshold of 50% was not passed.
