Things went well after the farmer was expelled. All the animals worked together. They made rules to ensure the old ways did not come back to the farm. However, the pigs decided that "all animals are equal, but some animals are more equal than others." They took up residence in the farmhouse, which was prohibited by the rules. They dominated the other animals. The farm became even worse than it was when the human farmer was in charge. Some pigs banded together and formed a powerful group: The Great Outstanding Pigs. The GOP made the other pigs, and all the other animals, work long hours under intolerable conditions.
Then, a different pig took over the GOP--the Great Orange Pig. What followed may well have challenged democracy in the twenty-first century.
