That's a logical interpretation of it as well but I put more focus on how Hitler gained populist support and that was largely through what he spoke about in his speeches. We all know Hitler was brilliant at giving speeches....which ultimately shifted popular opinion in favor of Hitler's "restoring the glory of Germany" agenda. If you look at Hitler's propaganda videos the message is very clear: Hitler was a true statesman and a man of the people and working class Germans.

The anti-communist element you speak of is also true because there was a small communist party within Germany that was fighting for power as well. Stormtrooper men were often seen fighting with these communist supporters when Hitler was rising to power. I could see the communist fear from Russia being quite strong in your average German as well.
