Majority Line

51 / 100

Democrats need 51 seats — the GOP Vice President breaks 50-50 ties. Model: rating-implied margins + a D+0.5 national environment (generic ballot D+6.8) + correlated national error (±3 pts, weighted by historical polling misses) + independent race-level error (±4 pts) across 20,000 simulated elections. Results are fixed for a given set of ratings — they only move when the forecast itself changes.
