You are a bird, and a grassroots organizer for the Avian Advancement Party in the nation of Animalia. Your party has raised enough money for exactly two campaigns, and there are four cities to choose between. The analysts have handed you, for each city, a table of how voters change party in a single year. Elections come every four years. These matrices and the 2024 populations are the analysts' report — you cannot edit them here, because the argument you are being asked to make has to survive the numbers you were given. Step each city forward and see which two are worth the money.
Row = the party someone belonged to in 2024. Column = the party they move to within one year. Read across a row and the numbers should total 1.
