Model Colorado State Senate District 4 in five steps

  1. Set the candidates. Name the contenders for the Colorado State Senate District 4 (or keep the generic Democrat / Republican defaults). The map starts from real 2024 results in every precinct.
  2. Apply a swing. Move vote share statewide, or by demographic cohort, with a slider. The map and the running tally recompute instantly.
  3. Model turnout. Mobilize or depress turnout for any group — turnout and persuasion are modeled separately, the way a real campaign thinks about them.
  4. Drill to precincts. Zoom from the state down to individual precincts and override any of them by hand.
  5. Roll up & share. Roll the result up to chamber control, then publish a shareable, frozen link to your scenario.
