"True strength is a quality of few men, or else we would not have the word hero. The masses consist of average men, democrats. But a hundred blind men do not make one seer, a thousand cowards do not make a hero, a hundred thousand parliamentarians do not make a statesman.
Cowardly men choose the most cowardly as their leaders, so that they won't have to show courage; and they choose the stupidest among the stupid, so that everyone can have the feeling that he's a little better than the leader."
This is attributed to Hitler, but the only source comes from Konrad Heiden in his contemporary account "The Fuehrer", so take that into consideration.
