Napoleon prefers to work behind the scenes to build his power through manipulation and deal-making, while Snowball devotes himself, as Leon Trotsky did, to winning popular support through his ideas, passionate speeches, and success in debates with his opponent. Snowball seems to work within the political system, while Napoleon willingly circumvents it. Napoleon, for instance, understands the role of force in political control, as is made clear by his use of the attack dogs to expel Snowball from the farm.
