## Analysis

The evidence is overwhelming and consistent: D+23-26 PVI, Cook Solid D rating, incumbent Democrat running for reelection, 2024 general was all-Democrat (no Republican even advanced), Silicon Valley hasn't elected a Republican since the 1990s, and 2026 midterm under Republican president favors Democrats. The only downside risks identified are extremely low-probability tail events (major scandal, party switch, health crisis). This is not a case of LLM hedging toward 50% - the estimates are appropriately extreme given the evidence.
