Carroll was compelled to write about the rules of lawn tennis tournaments after talking to an acquaintance who was upset after he lost in the first round and then saw a player much weaker than himself make his way into the finals. Of course, they didn’t have seeding back then. Draws were composed randomly, so the best and second best players could very easily meet in the first round.
I am much indebted to it for explaining his complex system.
Carroll’s obsession with fairness also took him into the arena of elections. He wrote three pamphlets about elections. He was upset not just by unfairness in national elections, but also by unfairness in Oxford University elections. Imagine a university with an unfair system! Here is an article by Glenn C. Joy entitled “Ballots in the Belfry: Lewis Carroll and Voting Fairness”: file:///C:/Users/Owner/Downloads/NMWT_2002_Joy_BallotsInTheBelfryLewisCar.pdf .

Alice thought she had never seen such a curious croquet-ground in her life: it was all ridges and furrows: the croquet balls were live hedgehogs, and the mallets live flamingoes, and the soldiers had to double themselves up and stand on their hands and feet, to make the arches.
The live creatures make it a game of random chance rather than skill. They also make it wonderfully loopy and fun and imaginative. Could Carroll be mocking here a Victorian game that is a bit staid and stuffy? He wants rules that are fair and that work, but he also loves defying rules and logic.
Alice says to the Cheshire Cat:
“I don’t think they play at all fairly,” Alice began, in rather a complaining tone, “and they all quarrel so dreadfully one ca’n’t hear oneself speak—and they don’t seem to have any rules in particular: at least, if there are, nobody attends to them—and you’ve no idea how confusing it is all the things being alive: for instance, there’s the arch I’ve got to go through next walking about at the other end of the ground—and I should have croqueted the Queen’s hedgehog just now, only it ran away when it saw mine coming.”
On the one hand, I hear in Alice’s petulance Lewis Carroll’s frustration with a world that does not work logically. He was, after all, a logician. On the other hand, how much more fun and wondrous is a game with live creatures than a game with plain wooden sticks and wire wickets? Just look at this picture of a real Victorian croquet game. It is not at all inspiring.
The caucus race is another illogical and unfair game. Again, the course is uneven and the rules are unclear.
First it [the Dodo] marked out a race-course, in a sort of circle, (“the exact shape doesn’t matter,” it said,) and then all the party were placed along the course, here and there. There was no “One, two three, and away!” but they began running when they liked, so that it was not easy to know when the race was over.
What on earth would Carroll have made of this year’s Iowa caucuses? In Alice in Wonderland, when everyone asks the Dodo who has won the caucus race, he says: “Everybody has won, and all must have prizes.” What if the election in Iowa doesn’t eliminate any candidates? What if everyone wins and keeps running around in “a sort of circle” endlessly? It feels as though this has already happened. Carroll was eerily prescient.
