Historical Data Explorer
County and state presidential returns from 2000 through 2024, organized to show how each place moved over time, how far it diverged from the nation, and which states tracked their own statewide trend most closely.
Correlation normalizes each state's movement against the national shift. A score of 100 indicates near-perfect alignment with nationwide change.
The overview page now loads the prebuilt state totals file directly, while individual state pages fetch their own shard for faster map and table rendering.
