Modes

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.

Political Categories

Category names are just shorthand for margin ranges:

• Annihilation: ≥40%
• Dominant: 30-39.99%
• Stronghold: 20-29.99%
• Safe: 10-19.99%
• Likely: 5.50-9.99%
• Lean: 1.00-5.49%
• Tilt: 0.50-0.99%
• Tossup: <0.50%

Example: "Safe Republican (10-19.99%)" means the Republican candidate leads by 10-19.99 percentage points (two-party margin).
