Decided to read 1984 again for reasons that should be obvious; I'm amazed on each and every page.

Here, in 1949, Orwell is describing the Low Information Voter, or Useful Idiot, as represented by the proles:

"To keep them in control was not difficult. A few agents of the Thought Police moved always among them, spreading false rumors and marking down and eliminating the few individuals who were judged capable of becoming dangerous; but no attempt was made to indoctrinate them with the ideology of the Party. It was not desirable that the proles should have strong political feelings. All that was required of them was a primitive patriotism which could be appealed to whenever it was necessary to make them accept longer working hours or shorter rations. And even when they became discontented, as they sometimes did, their discontent led nowhere, because, being without general ideas, they could only focus it on petty specific grievances. The larger evils invariably escaped their notice"
