Maybe it’s a stretch to call Daenerys a Leninist, but she has his strong sense of entitlement, of thinking that she knows what is best for the common people and how to liberate them. She rules together with a small vanguard of close advisers, who may not always agree on strategic considerations, but nevertheless are for ever loyal to their leader. Spending most of her days in exile, she gathers her forces and waits for the right moment to return to the motherland. Her righteousness can lead to unnecessary cruelty, even if the ambition of universal liberation is admirable.
Jon Snow combines Fidel Castro’s strategic mind in pulling together a populist alliance against “the enemy in the North” with Che’s bearded charisma as a fighter. He’s not the most democratic leader, and god knows what he’ll become if he gets complete power, but being in the front-line and earning his people’s trust are central to his brand of leadership. Presenting himself as a down to earth guy, he still has all the confidence of being from a “high born” family.
And yes, Cersei certainly has an element of Stalinism to her. Being the ultimate real politician, there isn’t much room for ideology here, and any agreement or tactical alliance is okay as long as it consolidates her own power. Emerging from the shadows of seemingly more powerful people, she gradually extends her power by crushing one rival after another.
The guys who would rather die standing than live on their knees, aka the Wildlings, aka the Free Folk, are the anarchists of the realm. With a slight tendency to glorify violence and a deep mistrust of all kings and queens, they live by their own rules on the fringes of society. While democracy isn’t very highly regarded in the rest of the Seven Kingdoms, the Free Folk gets their general assembly together whenever it is decision making time. Mance Ryder is their Makhno or Durruti, someone who is looked up to not as a “rightful heir”, but for exceptional organising and fighting skills.
