Democrat Political Future Index
Composite of Democrat party-line contests across all levels of office in the United States
A probability-based index uses a 50–150 scale. 100 is neutral. The level minus 50 is the implied win probability. A constituent market keeps its own 0–100 Yes probability. See the methodology overview for how the level is built. The Governance catalog holds the formal methodology and factsheet.
