"Friends of Russia here think of the dictatorship of the proletariat as merely a new form of representative government, in which only working men and women have votes, and the constituencies are partly occupational, not geographical. They think that "proletariat" means "proletariat", but "dictatorship" does not quite mean "dictatorship". This is the opposite of the truth. When a Russian Communist speaks of dictatorship, he means the word literally, but when he speaks of the proletariat, he means the word in a Pickwickian sense. He means the "class-conscious" part of the proletariat, i.e., the Communist Party."
