Methodology and data coverage
Data coverage
3 of 3 branch markets are available.
Methodology
The scale runs from +50 D to 0 to +50 R. Zero means power is roughly even.
Each branch blends market odds for the next election (75%) with current control (25%). Congress also uses seat-count and margin markets. Shutdown risk pulls the score toward zero.
The control and market expectations section shows the split: current control, market odds, and the final blend. The trend chart is rebuilt from daily snapshots.
