Vulnerability Index AD-120
Base lean: R+31
- Limited contested election data — registration lean used as primary signal
- Ran uncontested in most recent election
Scenario model: ±5pt national environment shift applied to district base lean (R+31). Base lean blends voter registration (40%) with recent contested general election margins (60%), using up to the last 4 general elections with margins under 40 points. Ratings: Safe D/R = 15+ pts, Likely = 8–14 pts, Lean = 3–7 pts, Toss-up = within 2 pts. Generic ballot from Silver Bulletin (Nate Silver), as of 5/1/2026. Not a prediction — reflects structural competitiveness under different cycle environments.
