And after all, your pigs are far more intelligent than the other animals, and therefore the best qualified to run the farm—in fact, there couldn’t have been an Animal Farm at all without them: so that what was needed, (someone might argue), was not more communism but more public-spirited pigs.

Eliot was surely wrong to call Animal Farm "Trotskyite" but that was probably his way of noting that Orwell's critique of communism was coming from the left, not the right. This fits with another fun fact: the most famous fan of Orwell's unpublished preface is Chomsky, who has been championing it for decades.
