I always hear how great of a politician he was and that's why the NSDAP got in power but people never go into specific examples or details.
One of his most significant characteristics in his politics was his oratory skills. Here you can see he is a very eccentric speaker who was very vocal, very passionate and intense. He used his intense words to sway an entire nation into following him and his ideas. He often practiced his speeches late into the night in front of a mirror to make them suitable to speak before the nation.
