Thesis

Polymarket prices Steyer at 33.5% (Vol $19.8M). EHIQ at 30% — 3.5pp fade. CNN debate refined the Klein-interview Steyer read modestly downward. Money-with-message work since 2020 is real (split roll + water's edge tax loopholes named in Klein interview), but the broader Dem field's combined attack on his billionaire register is durable. Establishment + Hispanic coalition consolidation around Becerra still constrains Steyer's ceiling. Sleeper risk: Mahan's 'private prisons / ICE detention centers' attack on Steyer landed in debate (single-source — verify before external publish).
