Serge, very good as far as you went- but there was another vote March 5 1933.   A wild election with 88% voting,  it was far from free, with Chancellor Hitler and his NSDAP intimidating their opponents, yet the Nazis still couldn't get a majority: only 43.9%.  Their naive partners, the arch-conservative German Nationalists were just 8%, giving the government a bare 51.9% majority.  Of the other main parties, the Socialists had 18.3%, Communists 12.3%, and the  two moderate conservative  Catholic parties 13.9%.
The Nazis had but 288 of the 647 Reichstag seats, the Nationalists 52.
However, on March 23, the Nazis and Nationalists were easily able to  pass the democracy-ending "Enabling Act" which required a two-thirds vote--  most all  the Communist deputies as well as many Socialists had been arrested and weren't present; and the moderate conservative parties gave in to threats and promises.  At the end, only the heroic 94 Socialists were left to vote "NO!"  
Brutal tyranny took over.
