Model California's 12th Congressional District in five steps
- Set the candidates. Name the contenders for the California's 12th Congressional District (or keep the generic Democrat / Republican defaults). The map starts from the canonical mixed-grain 2024 presidential baseline.
- Apply a swing. Move vote share statewide, or by demographic cohort, with a slider. The map and the running tally recompute instantly.
- Model turnout. Mobilize or depress turnout for any group — turnout and persuasion are modeled separately, the way a real campaign thinks about them.
- Explore local geography. Zoom from the state through counties to the finest supported reporting grain and adjust the places available in the model.
- Roll up & share. Roll the result up to chamber control, then share the exact versioned scenario.
