The Arithmetic of the Youth Vote

You are running a presidential campaign in 2024. Every group of voters is on this page. Raise a group's turnout, change how it splits between Harris and Trump, and watch what happens to the national result.

This is arithmetic, not a forecast. You are choosing what would happen if a group turned out or voted differently — not predicting that any campaign could make it happen. The national result is simply the sum, over groups, of share of eligible citizens × turnout × vote split.
