Margins: colors show the two-party margin (absolute value of Rep% - Dem%). Darker = less competitive.
Winners: solid color by winner (D/R), regardless of margin size.
Shift: change in signed margin vs the nearest available prior election for that contest (e.g. 2020->2024). Positive = more Republican; negative = more Democratic.
