Model Pennsylvania State Senate District 4 in five steps
- Set the candidates. Name the contenders for the Pennsylvania State Senate District 4 (or keep the generic Democrat / Republican defaults). The map starts from real 2024 results in every precinct.
- Apply a swing. Move vote share statewide, or by demographic cohort, with a slider. The map and the running tally recompute instantly.
